New NWI for geofeed?
by denis walker 14 Apr '22

14 Apr '22

Colleagues [Apologies for the length of this email...] The chairs would like to suggest creating a new NWI for the "geofeed:" attribute and suggest the following draft Problem statement and Solution definition. If there is agreement on this the RIPE NCC will do an impact assessment including legal review and summary of what the other RIRs are doing. There has already been quite a discussion in the WG on this issue with a lot of support. So hopefully we can reach a consensus quickly, at least on setting up the NWI and starting the impact assessment. Having read the latest draft IETF docs, there are some outstanding questions. Comments and changes are welcome... cheers denis co-chair DB-WG Problem statement Associating an approximate physical location with an IP address has proven to be a challenge to solve within the current constraints of the RIPE Database. Over the years the community has chosen to consider addresses in the RIPE Database to relate to entities in the assignment process itself, not the subsequent actual use of IP addresses after assignment. The working group is asked to consider whether the RIPE Database can be used as a springboard for parties wishing to correlate geographical information with IP addresses by allowing structured references in the RIPE Database towards information outside the RIPE Database which potentially helps answer Geo IP Location queries The IETF is currently discussing an update to RPSL to add a new attribute "geofeed: url". The url will reference a csv file containing location data. Some users have already started to make use of this feature via the "remarks: geofeed: url". It is never a good idea to try to overload structured data into the free format "remarks:" attribute. This has been done in the past, for example with abuse contact details before we introduced the "abuse-c:" attribute. There is no way to regulate what database users put into "remarks:" attributes. So even if the new "geofeed:" attribute is not agreed, the url data will still be included in the RIPE Database. Currently there are 24,408 INETNUM and 516,354 INET6NUM objects containing a "remarks: geofeed: url" attribute in the database. These have 7,731 distinct values in the INETNUMs and 1,045 distinct values in the INET6NUMs. Solution definition Implement a new "geofeed:" attribute according to the IETF's definition. Although the IETF has not yet concluded discussions on this attribute we can still implement it in the RIPE Database RPSL data definition. The RIPE Database already has many local differences to the RPSL standard. As expressed in the Problem statement, users are already using the geofeed data by overloading the "remarks:" attribute. That is a dirty hack which should be avoided. An invalid formated url will be a syntax error. The RIPE NCC will perform a one time conversion of the existing data to convert "remarks: geofeed: url" to "geofeed: url". If an update then contains a "remarks: geofeed: url" attribute, the update will be successful and the response should include an appropriate Warning message. At some point in the (near) future, this could be changed to an update failure as a syntax error. An update containing a "geofeed:" and a "remarks: geofeed:" attribute or more than one "remarks: geofeed:" will be a syntax error. The resource holder should be able to create, modify, delete the "geofeed:" attribute in allocation objects. Questions: -Should the database software do any checks on the existence/reachability of the url as part of the update with an error if the check fails? -Should the RIPE NCC do any periodic repeat checks on the continued existence/reachability of the url? -Should the RIPE NCC do any periodic checks on the content structure of the csv file referenced by the url? -Should the Solution definition define how this will be adopted into RDAP or should we simply ask the RIPE NCC to define this in their impact assessment? -The RIPE Database contains hierarchical address space objects. Should it be acceptable for "geofeed:" attributes to exist at multiple levels within a specific hierarchy? -Suppose a geofeed csv file referenced by a /16 INETNUM object contains location data for the whole /16. Then a more specific /24 INETNUM object references another geofeed csv file that contains conflicting location data for this /24. Should this be a concern for the RIPE Database? -Should geofeed data be inherited? If you query for a /24 that does not contain a "geofeed:" attribute, but a less specific /16 does contain a "geofeed:" attribute, should this data be returned? In other words could it be used in a similar way to "abuse-c:"? -Thinking ahead to how people will actually deploy this data and what short cuts they could make. It is said that when reading a geofeed csv file, consumers of the data should ignore all data within that file not directly concerning the address space queried in the RIPE Database. Could you therefore create a single csv file with location data for all your address space and reference the same file in all your RIPE Database address objects? The address space owner could rely on the data consumer to pick out the correct piece of data for the relevant address space. The manager of the csv file then only has to work with one file. If this is possible and does happen (which the IETF doc 'Finding geofeeds' seems to suggest is possible for unsigned geofeed data), would it therefore make sense to apply "geofeed:" hierarchically as with "abuse-c:"? Allow a single, default "geofeed:" attribute in the ORGANISATION object to be applied to all that organisations address space, with the option of specific localised "geofeed:" attributes in address space objects. That could be a neater solution, and easier to setup, than applying thousands of references to the same geofeed file at a more specific level in the database. -Relating to the above 3 questions, should geofeed data only be considered applicable if returned by a specific geofeed locater application which takes into account the hierarchical nature of address space in the database? Otherwise do the standard database query mechanisms have to take into account this hierarchy and locate the most specific "geofeed:" attribute from the less specific objects? -Should/could the RIPE Database return the csv file as part of the query? If so should the file be cached (for how long?) to avoid too many downloads? -Should we only allow HTTPS urls? (Which the IETF doc 'Finding geofeeds' seems to suggest) -Should the RIPE NCC go ahead and implement this now, with our own set of RIPE rules? Or should we try to coordinate this and agree a set of common rules between all the RIRs before any deployment in the RIPE Database? -For the legal review, there are 2 statements in the IETF doc 'Finding geofeeds' which may be of concern: *[RFC8805] geofeed data may reveal the approximate location of an IP address, which might in turn reveal the approximate location of an individual user. Unfortunately, [RFC8805] provides no privacy guidance on avoiding or ameliorating possible damage due to this exposure of the user. In publishing pointers to geofeed files as described in this document the operator should be aware of this exposure in geofeed data and be cautious. All the privacy considerations of [RFC8805] Section 4 apply to this document. *It is significant that geofeed data may have finer granularity than the inetnum: which refers to them. It is clear that the RIPE NCC cannot prevent this data being referenced by objects in the RIPE Database. It is already being referenced from "remarks:" attributes. Perhaps the RIPE NCC should require (as part of their service agreement) that it's members obtain written consent from their customers to publish this location data, or at least inform the customers in writing that it will be published. Also, although RFC8805 says postcode is deprecated it is still provided for in the csv files. So anyone can still enter location data to this detail. -The IETF doc 'Finding geofeeds' suggests that geofeed information 'will be' available in bulk accessed whois data. In view of the privacy concerns above, is this likely? -The IETF doc 'Finding geofeeds' says "To minimize the load on RIR whois [RFC3912] services, use of the RIR's FTP [RFC0959] services SHOULD be the preferred access." Is the RIPE NCC expected to download all the geofeed files and make them available through their FTP service? -The IETF doc 'Finding geofeeds' states that consumers of the geofeed data MUST NOT access this data in real time via the RPSL servers 'too frequently' or at 'magic times like midnight'. Some users will do whatever they want to do if they are able to do, regardless of any statements to the contrary. Should the RIPE NCC enforce such access rules by some means?

NWI-4 - role of status: field in multivalued status context - reprise
by Carsten Schiefner 08 Jun '21

08 Jun '21

Dear all - after a quick chat with Dennis on this, he encouraged me to toss this into the seemingly stalled, but not yet dead debate: Right now, only the "inet[6]num:" attribute is the primary key to, of or for inet[6]num objects. I wonder if it would be possible to make the tuple ("inet[6]num:","status:") the primary key instead: that should solve the challenge to have an assignment that shall have the size of an allocation. In case this has been exhaustedly discussed here already, please excuse my ignorance - I then obviously have failed to spot the respective contribution in the archives. All the best, -C.

Restricting WHOIS searches to type: netname
by Ronald F. Guilmette 29 May '21

29 May '21

One of the helpful options provided by the RIPE WHOIS server is the --types option which provides a list of what specific object types a given set of query results may be restricted to. That list is as follows: inetnum inet6num as-block aut-num as-set route route6 route-set inet-rtr filter-set peering-set rtr-set domain poetic-form poem mntner irt key-cert organisation role person Can anyone explain to me why "netname" is not on the above list? I would like to be able to query the data base for "ABC" but restrict the query so that I only get back the records for the dozen or so IP blocks whose registrants have (unwisely?) elected to label their networks as "ABC", while NOT also getting back all 16 or so of the organisation objects whose org-name: field contains the substring "ABC", much less the numerous and additional person and role records whose person: and role: fields also and likewise contain the substring "ABC". If I can selectively query just for poems, is there some reason why netnames deserve less respect? And as long as we are on the subject, may I safely infer from the presence, in the data base, of a dozen different networks named "ABC" that no attempt has ever been made to insure uniqueness of netnames within the data base? Are netnames even restricted, as they seem to be, to having a form which is rather strikingly reminicent of actual unique data base handles, i.e. consisting of only alphanumerics and hyphens? Regards, rfg P.S. I do not mean to pick on RIPE specifically here. A quick check reveals that whois.apnic.net and whois.afrinic.net also fail to support selective querying for just netnames... although in those two cases selective quering for poems is also not an option... a sad fact that has left me rather entirely bereft, as I'm sure you can all imagine.

created: field value
by Ronald F. Guilmette 29 May '21

29 May '21

My apologies to all. I don't intend to be a complainer. I'm just trying to understand fully what's going on in the data base. I must say however that I am getting the impression that the value in the created: field for some (many?) inetnum objects may not be entirely reliable, or even entirely consistant with other available historical data. Example: inetnum: 138.201.0.0 - 138.201.255.255 netname: HETZNER-RZ-BLK-ERX4 descr: Server Block country: DE org: ORG-HOA1-RIPE admin-c: HOAC1-RIPE tech-c: HOAC1-RIPE status: LEGACY mnt-by: HOS-GUN mnt-lower: HOS-GUN mnt-routes: HOS-GUN mnt-domains: HOS-GUN created: 1970-01-01T00:00:00Z last-modified: 2019-12-04T13:10:40Z source: RIPE Given that 1970-01-01T00:00:00Z is rather well known to be the beginning of UNIX time (i.e. time: 0) I could not help but be a bit suspicious of the value in the created: field of the record shown above. A quick look at version #1 of the data base object for the 138.201.0.0/16 block suggests that a rather more appropriate value might have been something more like 2003-12-11T17:11:00Z ======================================================================== % Version 1 of object "138.201.0.0 - 138.201.255.255" % This version was a UPDATE operation on 2003-12-11 17:11 inetnum: 138.201.0.0 - 138.201.255.255 remarks: remarks: This inetnum has been transfered as part of the ERX. remarks: It was present in both the ARIN and RIPE databases, so remarks: the information from both databases has been merged. remarks: If you are the mntner of this object, please update it remarks: to reflect the correct information. remarks: remarks: Please see the information for this process: remarks: http://www.ripe.net/db/erx/erx-ip/network-138.html remarks: remarks: **** INFORMATION FROM ARIN OBJECT **** remarks: netname: NETCS-CUST4 descr: netCS Informationstechnik GmbH descr: Feuerbachstrasse 47/49 descr: D-1000 Berlin 41 remarks: country: DE remarks: changed: hostmaster(a)arin.net 19900523 remarks: changed: hostmaster(a)arin.net 20010220 remarks: **** INFORMATION FROM RIPE OBJECT **** netname: KIEZ-NET1 descr: Kiez-Net WAN country: DE rev-srv: DNS-A.Kiez.Net rev-srv: DNS-B.Kiez.Net status: ASSIGNED PI mnt-by: KIEZ-MNT source: RIPE # Filtered Am I the only one who thinks so? It is certainly my hope that the value in the created: field should accurately reflect the date & time when any given object was in fact created within the RIPE WHOIS data base. Is there any compelling reason why this should ever not be the case? Regards, rfg

BOGON => 103.86.68.0/22
by Ronald F. Guilmette 28 May '21

28 May '21

My apologies to all. My interests and attention are getting pulled in so many different directions these days that I tend to forget the answers to questions that I seem to vaguely remember having already asked. So, at the risk of repeating myself, what's the current policy on stale route objects in the data base that refer to current bogon address space? I'm specifically interested in 103.86.68.0/22 at the moment. route: 103.86.68.0/22 origin: AS131477 mnt-by: HUAJUAN-MJJ-MNT created: 2018-02-24T19:00:10Z last-modified: 2018-09-04T19:09:05Z source: RIPE-NONAUTH

status: LEGACY -- Stranger and stranger
by Ronald F. Guilmette 28 May '21

28 May '21

Regarding one of the "LEGACY" blocks mentioned in my prior email, on a whim I decided to take a look at the full history of the block. That full history is reproduced below. This history causes me to have even more questions than I have already asked. I'm still totally befuddled by the fact that this block apparently is and always was marked as "status: LEGACY", even though it's original allocation date still seems to be 2015-09-23, which seems relatively recent to me. Just as perplexing is the apparent direct transfer of the block from a department of the UK government to a private for-profit Internet company. Has the UK government been so hard up for cash in recent years that it has taken to selling off any spare /16 blocks that it happens to have lying around? If so, who should I talk to about placing a bid for the next one they decide to unload? ======================================================================== % Version 1 of object "51.155.0.0 - 51.155.255.255" % This version was a UPDATE operation on 2015-09-23 15:10 inetnum: 51.155.0.0 - 51.155.255.255 netname: UK-DWP descr: UK Government Department for Work and Pensions country: GB status: LEGACY mnt-by: DWP-MNT created: 2015-09-23T13:10:05Z last-modified: 2015-09-23T13:10:05Z source: RIPE ======================================================================== % Version 2 of object "51.155.0.0 - 51.155.255.255" % This version was a UPDATE operation on 2015-09-23 15:15 inetnum: 51.155.0.0 - 51.155.255.255 netname: UK-DWP descr: UK Government Department for Work and Pensions country: GB org: ORG-DWP1-RIPE status: LEGACY mnt-by: DWP-MNT created: 2015-09-23T13:10:05Z last-modified: 2015-09-23T13:15:16Z source: RIPE ======================================================================== % Version 3 of object "51.155.0.0 - 51.155.255.255" % This version was a UPDATE operation on 2015-11-05 17:51 inetnum: 51.155.0.0 - 51.155.255.255 netname: UK-ZEN descr: Zen Internet Limited country: GB org: ORG-DWP1-RIPE status: LEGACY mnt-by: ZEN-MNT created: 2015-09-23T13:10:05Z last-modified: 2015-11-05T16:51:50Z source: RIPE ======================================================================== % Version 4 of object "51.155.0.0 - 51.155.255.255" % This version was a UPDATE operation on 2015-11-05 18:43 inetnum: 51.155.0.0 - 51.155.255.255 netname: UK-ZEN descr: Zen Internet Limited country: GB org: ORG-ZIL1-RIPE status: LEGACY mnt-by: ZEN-MNT created: 2015-09-23T13:10:05Z last-modified: 2015-11-05T17:43:45Z source: RIPE ======================================================================== % Version 5 of object "51.155.0.0 - 51.155.255.255" % This version was a UPDATE operation on 2019-07-04 12:43 inetnum: 51.155.0.0 - 51.155.255.255 netname: UK-ZEN descr: Zen Internet Limited country: GB org: ORG-ZIL1-RIPE status: LEGACY mnt-by: ZEN-MNT mnt-by: ZEN-NOC-MNT created: 2015-09-23T13:10:05Z last-modified: 2019-07-04T10:43:36Z source: RIPE ======================================================================== % Version 6 (current version) of object "51.155.0.0 - 51.155.255.255" % This version was a UPDATE operation on 2020-02-03 12:55 inetnum: 51.155.0.0 - 51.155.255.255 netname: UK-ZEN descr: Zen Internet Limited country: GB org: ORG-ZIL1-RIPE status: LEGACY mnt-by: RIPE-NCC-LEGACY-MNT mnt-by: ZEN-MNT mnt-by: ZEN-NOC-MNT created: 2015-09-23T13:10:05Z last-modified: 2020-02-03T11:55:22Z source: RIPE

Questions about status: LEGACY
by Ronald F. Guilmette 28 May '21

28 May '21

Could someone be so kind as to enlighten me about the intended semantics of "status: LEGACY"? I'm back to trying to do parsing of the data base, en mass, and I've just now noticed that the annotation "status: LEGACY" within a given inetnum record may not mean what I thought it meant. (And by the way, there seem to be several tens of thousands of inetnum records in the data base, at present, which are all marked as "status: LEGACY".) Here are just a couple of randomly chosen samples that are confusing me: inetnum: 51.155.0.0 - 51.155.255.255 netname: UK-ZEN descr: Zen Internet Limited country: GB org: ORG-ZIL1-RIPE admin-c: RT1337-RIPE tech-c: ZIRA1-RIPE status: LEGACY mnt-by: RIPE-NCC-LEGACY-MNT mnt-by: ZEN-MNT mnt-by: ZEN-NOC-MNT created: 2015-09-23T13:10:05Z last-modified: 2020-02-03T11:55:22Z source: RIPE inetnum: 51.155.91.64 - 51.155.91.71 netname: ZEN20210525-NOC-NYCOMM-LIMITED descr: Nycomm Limited descr: leased-line country: GB admin-c: RT1337-RIPE tech-c: ZIRA1-RIPE status: LEGACY mnt-by: ZEN-NOC-MNT created: 2021-05-25T16:49:09Z last-modified: 2021-05-25T16:49:09Z source: RIPE In what sense is the first inetnum record above denoting a "LEGACY" block? The block appears to have been first assigned by RIPE to ORG-ZIL1-RIPE on 2015-09-23. Aren't LEGACY blocks just the ones left-over from the very old days? I have the same questions also for the second inetnum record shown above, which is a sub-assignment / sub-allocation of the first one. Well, here's another one. This also seems rather un-LEGACY, based on the apparent creation date. inetnum: 162.55.0.0 - 162.55.255.255 netname: DE-HETZNER-19920803 country: DE org: ORG-HOA1-RIPE admin-c: HOAC1-RIPE tech-c: HOAC1-RIPE status: LEGACY mnt-by: RIPE-NCC-LEGACY-MNT mnt-by: HOS-GUN mnt-lower: HOS-GUN mnt-domains: HOS-GUN mnt-routes: HOS-GUN created: 2019-11-18T15:01:35Z last-modified: 2019-11-18T15:01:35Z source: RIPE I'm sure that there is a perfectly rational explanation for all of this. I would greatly appreciate it if someone would guide me to it. Whatever is going on here, I obviously didn't get (or didn't read) the memo. Regards, rfg

What is the RIPE Database in 2021?
by denis walker 18 May '21

18 May '21

Colleagues There was an interesting presentation in the Address Policy session at RIPE 82 this morning by Remco. He raised a number of issues about what exactly is the RIPE Database, what does it do and who does it do it for? The history of the RIPE Database is quite well known (within the industry). It developed as a means to assist resource holders and network operators with 'Internet operational issues'. It also helped the RIPE NCC, as a registry, to allocate Internet resources fairly and uniquely as and when needed. It's development and operation was and is funded by the RIPE NCC membership. But what is the RIPE Database now, in 2021? What will it be in the coming years, decades? Who will use it, who will pay for it, who gets to decide what is in it? The RIPE Database has evolved over the last 20+ years. It is much more now than just a tool for 'Internet operational issues'. It has a more diverse collection of data consumers. But is it still locked in the hands of a very small set of vocal users whose mindset is also locked in the historical context of the database? Too often in discussions about policies and database features we hear the phrases "It's not the purpose of the RIPE Database to do 'abc'" and "It's not the function of the RIPE NCC to do 'xyz'". Are the people saying this RIPE NCC members who are paying for the database? Is that an issue? I don't know. Maybe it is time to stop thinking of the RIPE Database only in terms of 'Internet operational issues'. Whether people have accepted it yet or not, the RIPE Database is a Public Registry of Internet resources. It serves a similar important function in society as a Land Registry, Company Registry, Vehicle Registry, but on a pan national scale. It's usage goes beyond the historical resource holders, engineers and network operators. Along with the function of managing the resources is the importance to the wider public of knowing who is the [owner, user, registrant, operator] (pick your own word) of an Internet resource. To fulfill its role as a Public Registry perhaps it needs more data not less data. But that has to be the right data. The Database Task Force (DBTF) is considering a recommendation to make IPv4 assignments in the RIPE Database optional. That could lead to the complete removal of 94% of the IPv4 resource detail in the database. Rather than considering making IPv4 assignments optional, maybe what we should be considering is making more IPv6 assignment detail mandatory. Do we need to know who sits behind any of those aggregated blocks? Do we need to start filling in this detail before we go too far down the IPv6 road making the backlog difficult to fill in? Who should make decisions in the future about the purpose, use, access, content of the RIPE Database? Should it be tied to (historical) address policy? Or should it be based more on a wider scope as a Public Registry for the benefit of society? Should the RIPE NCC members, who are paying for the database, have any priority in defining it's current and future use? If that becomes an issue should the RIPE Database be funded independently of the RIPE NCC membership? These are questions I had expected the DBTF to consider. Unfortunately I feel the scope of their work has been too narrowly focussed on current database operational functionality and historical purposes rather than current and future usage. The first heading in the draft requirements document is "What is the RIPE Database?". But it only talks about operational issues. The DBTF clearly stated it is only reviewing the database functionality. I'm not sure if you can define the requirements of the functionality without first considering the full scope of the purpose and usage and the context of the database in the industry and society. To be fair to the DBTF, their charter also focuses on database functionality. Maybe there has been a misunderstanding of the full meaning of 'functionality': noun (Oxford English Dictionary) 1.the quality of being suited to serve a purpose well; practicality. "I like the feel and functionality of this bakeware" 2.the range of operations that can be run on a computer or other electronic system. "new software with additional functionality" The draft document seems to focus on the second definition based on a historical view of the first definition. Also considering: The Business Requirement Document (BRD) describes the high-level business needs whereas the Functional Requirement Document (FRD) outlines the functions required to fulfill the business need. BRD answers the question what the business wants to do whereas the FRD gives an answer to how should it be done. The draft document from the DBTF is more like the FRD. It outlines the functions required to fulfill the historical operational needs. We are still missing the BRD for the RIPE Database in 2021+. We don't have a clear understanding of what we want the RIPE Database to do and who for. Thanks Remco for a very timely presentation. (Although you did still keep referring to 'operational issues' which keeps the discussion locked into a historical context.) I look forward to further discussion on this topic... cheers denis co-chair DB-WG
