New NWI for geofeed?
by denis walker 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?
