Using the RIPE Database for IPAM
by denis walker 04 Oct '23

04 Oct '23

Colleagues Do you use the RIPE Database as your IPAM solution? If so, read on.... The RIPE NCC has done a brief review of the recommendations made by the DB Task Force (DBTF). You can find it here: https://www.ripe.net/participate/ripe/tf/rdb-requirements-tf/initial-analys… There is one point in the summary that I disagree with: One recommendation can be implemented immediately by the RIPE NCC: - 3. Using the RIPE Database as an IPAM solution The recommendation from the DBTF was: "The task force recommends limiting and discouraging the use of the RIPE Database as an enterprise IPAM solution." This has not yet been discussed by the community and there is no consensus on this recommendation. So the RIPE NCC should not be doing anything to implement this recommendation. There are a number of points relating to this. The first BoF held by the DBTF had 46 participants. They had some polls about IPAM: Where do you hold your canonical IP address assignment details? (13 answers) Internal database or IPAM system (5 - 38%) RIPE Database (5 - 38%) Internal database for detailed assignments and RIPE database for allocations (3 - 23%) What should we do about the IPAM use of the RIPE Database? (12 answers) We should discourage it (3-25%) We should tolerate it but provide restrictions and best practices (5-42%) We should promote it and facilitate it (4-33%) During the BoF some comments were also made on this: Shane's comment "IPAM seems to be an important thing" Nathalie said about 50% of people attending training courses over a number of years said they use the RIPE DB for IPAM. Also trainees said open source IPAM solutions often pull data out of the RIPE DB but have no functionality to push data to the RIPE DB. During the presentation by the DBTF in the DB-WG session at RIPE 83 Shane said (on IPAM): "if you had very light requirements for IPAM then maybe it is OK, but it's not really what it's for" "unable to find out if this [response] was based on misunderstanding of the question" "we think there are probably good ways to go forward with that, for example making hooks so that external IPAM solutions can hook into it...that makes sense, there are certainly many commercial vendors that make IPAM products who would be happy to use hooks, there are many ways that third parties could use this but probably not a requirement" So it looks like there are very mixed views on the use of the RIPE Database for IPAM. Some people also expressed surprise that so many people use the database for IPAM. It is clear that we don't actually understand who, how and why people use the database for IPAM. We need a better understanding of the how and why and the number of users doing this before we can make any decision about discouraging or encouraging this use of the database. Even to consider if IPAM should be defined as a purpose of the database. As we are talking about it, maybe now is the time to start this discussion. If you use the RIPE Database as your IPAM solution maybe you can offer some more details. cheers denis co-chair DB-WG

NWI-14 Authenticating References to Objects
by denis walker 19 Jun '23

19 Jun '23

Colleagues The chairs propose creating NWI-14 for expanding the optional use of the "mnt-ref:" attribute to protect objects from accidental or intentional mis-representation of responsibility. See slide 14 of this presentation for the problem definition: https://ripe78.ripe.net/presentations/129-RIPE78-Operational-Update.pdf We ask the RIPE NCC to add NWI-14 to the list. cheers denis co-chair DB-WG

proposal: disallow creation of new non-hierarchically named AS-SET objects
by Job Snijders 01 Dec '22

01 Dec '22

Dear DB-WG, Speaking in individual capacity. In RFC 2622 section 5 specifies the naming convention for AS-SET objects. https://www.rfc-editor.org/rfc/rfc2622#section-5.1 There basically are two styles: * "short" (example: AS-SNIJDERS) * "hierarchical" (example: AS15562:AS-SNIJDERS) Problem statement ================= In recent weeks a number of hypergiant cloud providers have faced the thorny effects of adversarial AS-SET object naming collisions between IRR databases. An example of this phenomenon is the existence of AS-AMAZON in both RADB and RIPE. According to https://www.peeringdb.com/net/1418 the RADB copy of the object is the the correct one and populated with a number of members entries. The RIPE one is empty, and not under control of Amazon. The existence of the AS-AMAZON object in the RIPE database might cause some operators to inadvertently apply empty prefix-filters to EBGP sessions which in turn causes various problems. It seems Amazon has no recourse to get the AS-AMAZON object removed from the RIPE database; because the existence of that object in the RIPE database does not violate any policies (as far as I know). But perhaps, going forward, this community can do a little bit more to help prevent similar situations from happening to others. Solution proposal ================= I think the solution is to - GOING FORWARD - disallow creation of new AS-SET objects which follow the 'short' naming style. The advantage of hierarchical naming is that the existing authorization rules as applied by the RIPE Whois Server database engine do a decent job of protecting/separating namespaces. 'Grandfathering' existing short-named objects ensures that implementation of this solution proposal causes minimal (if any) disruption to existing workflows. The RIPE database engine blocking creation of short-named AS-SETs might help nudge the industry towards making hierarchical naming the norm. Related work ============ Related work throughout the registry industry: IRRd version 4 forces new AS-SET objects to be structured hierarchically: https://github.com/irrdnet/irrd/issues/408 Kind regards, Job

NWI-10 Populating End User Organisation Country Attribute
by Edward Shryane 01 Dec '22

01 Dec '22

Dear colleagues, As I mentioned in the Operational Update during the DB-WG session at RIPE85 last week (slide 16): https://ripe85.ripe.net/wp-content/uploads/presentations/111-DB-WG-Operatio… *today* the DB team will populate the "country:" attribute in approximately 20K organisation objects in the RIPE database. This will be done for end user organisations with resources allocated or assigned by the RIPE NCC, with the country code value where the resource holder is legally based. We are continuing work internally on the remaining end user organisations without a country code, and software changes for synchronisation during resource requests. Regards Ed Shryane RIPE NCC

Issue with authorization in hierarchical as-sets
by Cynthia Revström 21 Nov '22

21 Nov '22

Hi DB-WG, While looking into the discussion about requiring hierarchical as-sets I wanted to see if all current hierarchical as-sets were authorized by the ASN holders and I found two separate issues (in my opinion). I could find at least two cases of hierarchical as-sets that were likely created before RIPE and RIPE-NONAUTH split. They are using APNIC ASNs and there are aut-num objects for both of them in RIPE-NONAUTH, but the as-sets are still in RIPE. I am not sure of the scope of this issue or if others consider it an issue, but it seems like that should possibly get cleaned up, or at least get checked out. I only tried to check if there were any occurrences of this, not trying to find a complete list, so I just checked for any 32-bit APNIC ASNs in the db dump using grep. For those who want to look at it, the grep command I used was: grep '^as\-set:\s*[Aa][Ss][1][3-6][0-9][0-9][0-9][0-9]' ripe.db.as-set There is also another issue related to authorization when it comes to hierarchical as-sets. While authorization by a maintainer listed as mnt-by on the aut-num object is required to create an as-set, that maintainer can then later be removed and there is no force-delete option like there is for inet(6)num delegations. I think that a force-delete option should be implemented so any maintainer with mnt-by on the relevant aut-num can delete an as-set. I think that it would also be helpful to introduce a "associated as-set objects" list to the DB web UI, just like there is for associated route objects currently. Something that could be an issue is the cleanup, what happens with an hierarchical as-set when the relevant ASN is de-registered? Maybe someone on the DB team could clarify? -Cynthia

2022-01 Policy Proposal Withdrawn (Personal Data in the RIPE Database)
by Angela Dall'Ara 17 Nov '22

17 Nov '22

Dear colleagues, The policy proposal 2022-01, "Personal Data in the RIPE Database” has been withdrawn. The goal of this proposal was to allow the publication of verified Personal Data in the RIPE Database only when justified by its purpose. The proposal is archived and can be found at: https://www.ripe.net/participate/policies/archived-policy-proposals/archive… Reason for withdrawal: The proposer felt that the scope of this proposal was too wide and decided to withdraw the proposal. Raised concerns like the potential consequences of the consent based publication of personal data and the efficacy of their verification might be addressed in future discrete proposals. Kind regards, Angela Dall'Ara Policy Officer RIPE NCC

Recognisition of Kosovo and adding of LIR signup options with Kosovo as well as XK in inet(6)num
by William Weber 17 Nov '22

17 Nov '22

Hi, As the Netherlands recognise the Republic of Kosovo as sovereign nation (see 1), and the EU does as well (see 2) there should be a way to include the proposed 2 letter country code (XK, see 3) as option for inet(6)num objects. The EU and other multinational organisation (IMF, SWIFT etc., see 4) use this code already since independence in 2008, and it is the currently reserved ccTLD for Kosovo as well. Kosovo also has a unique phone number prefix assigned (+383) by the ITU (see 5). It makes no sense that EU and AP is available (which are not countries, AP is not even in ISO-3166-2), but XK is not. I am aware the the X* series of codes is reserved and not permanently assigned, however UN Security Council resolution 1244/99 (see 6) mandates the use binding to all UN members. Please let me know how to bring in a draft resolution to adopt the ability to use Kosovo as legitimate country option in RIPE database objects, as well as the LIR sign up. It is the ONLY country that is recognised by both the Netherlands and the EU that cannot be used to sign up as a LIR and my client - a Telecoms company in Pristina that wants to stay anonymous at this time to avoid issues with Serbia - feels their right is violated by having to use either Serbia or Albania as billing location, and sees uncertainty in applicable laws and taxation with this.

Re: [db-wg] proposal: disallow creation of new non-hierarchically named AS-SET objects
by William Weber 16 Nov '22

16 Nov '22

> Limiting database updates to only accounts associated with LIR sounds reasonable. I cannot support this unless it is limited to AS-SET and similar; i for example hand out IPv6 prefixes to endusers and that would be impossible if they are unable to create MNT/Person/ORGs. I support this in general for AS-SET which makes no sense to have access to unless you have an ASN, but the startup maintainer process should stay the same. Same for ORGs - to request ASNs the enduser needs an ORG and i as LIR should not have to create that or even have MNT-BY on it. — William Sent from my iPhone > On 16.11.2022, at 12:00, db-wg-request(a)ripe.net wrote: > > Send db-wg mailing list submissions to > db-wg(a)ripe.net > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.ripe.net/mailman/listinfo/db-wg > or, via email, send a message with subject or body 'help' to > db-wg-request(a)ripe.net > > You can reach the person managing the list at > db-wg-owner(a)ripe.net > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of db-wg digest..." > > > Today's Topics: > > 1.

RIPE 85 session
by denis walker 08 Nov '22

08 Nov '22

Colleagues I would like to apologise for missing the DB-WG session at RIPE 85. I was taken ill the night before with severe gastric problems, which I have only recently recovered from. Now I am still recovering from covid also. I would like to thank my co-chair William for stepping in at the last minute to run the whole show. I have some comments to make on each presentation, but don't expect much from me this week. I will start to get my head round these issues again next week. cheers denis co-chair DB-Wg
