Re: [db-wg] Changes to the RIPE Database Acceptable Use Policy and Daily Limit Accounting

Hello, this discussion is annoying and in the circle. You're still trying to give the term "IP address" a different meaning than it has. IP address is IP addres. Period. It's not a subnet of any size, as you're trying to say. AUP clearly talks about IP address, not about end-user site etc. You put that in there arbitrarily. You are trying to give a strange interpretation of a standard technical term, which, however, has a clearly defined meaning. To defend yourself, you're thinking of hypothetical scenarios. But these can similarly occur with both IPv4 and IPv6. But as as a result, using IPv6 is a disadvantage now, you artificially penalize IPv6 more than IPv4. I can have IPv4 LAN with /24 and I'll no face any issue, but I'll have on LAN even with /64 IPv6. It's just stupid what you're doing. In fact, what the NCC tells us here is to turn off IPv6 and we'll be fine. And as it was already mentioned by Denis at db-wg, there're much more ways to scrap personal data if someone really wants to do that. But your pseudo-protection code is only throwing the baby out with the bath water. And create unnecessary problems for users on IPv6, thanks to developers incompetence (or laziness?). I understand, some employees and RIPE NCC doesn't understand IPv6 basics and make no difference between IP address and IP subnet (site). But there's a difference. Again. IPv6 address has 128 bits, not 64 bits, which NCC staff uses for AUP accounting. I raise question to services WG: How it's possible that an employees of RIPE NCC interprets standard terminology in such strange way and bends the written rules in the direction they are not written? Who approved the blocking of the entire subnet, when even AUP exactly says that IP addresses should be blocked in case of violation? Who is responsible for this creativity? I would like to hear the answers, because it seems that there is anarchy in NCC and the developers implements what they want, not what they should (with respect to published rules/documents). - Daniel On 8/6/24 3:45 PM, Edward Shryane wrote: > Hello Daniel, > >> On 6 Aug 2024, at 10:01, Daniel Suchy <danny(a)danysek.cz> wrote: >> >> Hello, >> >> On 8/5/24 3:32 PM, Edward Shryane wrote: >>> The current system is a compromise between allowing queries containing personal data, and complying with the Acceptable Use Policy: >>> https://www.ripe.net/manage-ips-and-asns/db/support/documentation/ripe-data… >> >> The current system is a design bug, not a compromise. >> > > It was a deliberate choice to account by /64 prefix size for IPv6 (the smallest subnet size) and /32 for IPv4 (the smallest prefix size). While it’s true that an IPv6 end user site could contain multiple users, this is the same for IPv4 where you could have a single public NAT address with many users behind it. However, within an IPv6 /64 end user site, the user is free to configure their global address. If we account for greater than a /64 then it becomes trivial for a user to change their host address and avoid the limit accounting. Changing the accounting to limit both by /128 and /64 prefixes complicates the implementation and operation of the system and the user must still comply with the AUP daily limit of 1,000 objects (it’s just harder to identify them). > > To avoid getting blocked, a user (one or many) must reduce the queries for objects containing personal information, no matter how the accounting is done. > >> Acceptable Use Policy clearly defines limits per IP address (without distinguishing whether IPv4 or IPv6). >> > > Using a /64 as the smallest subnet size is a reasonable compromise for the implementation, given the huge address space and how trivial it is to change host address, to avoid the accounting.

By default, RIPE Database queries are returning referenced personal data that the user did not ask for. Rather than change the accounting, we can change the default query behaviour.
