Dear All, I have a question regarding the IPv6 address assignment to cc level DNS server. If you don't have answer to this question please forward it to an appropriate working group - sorry for cross-posting this mail to two wg. We have here in Hungary a dilemma: - Traditionally, the IPv4 address of the primary cc level DNS server in of belonged to NIIF/HUNGARNET. - The DNS registration service a while ago was delegated to Council of Hungarian Internet Providers (ISZT) who is also operating the biggest Internet Exchange of Hungary (BIX). All big ISPs in Hungary (including NIIF/HUNGARNET) has right to do the registration via a special interface. - The IPv4 address of the primary cc level DNS server announced by NIIF/HUNGARNET. But ISZT is reorganizing its infrastructure to allocate address from a new PI type IPv4 address space to DNS servers. - The primary hu DNS server is connected to BIX - to be well connected. What IPv6 address space should we allocate to hu primary DNS server? 1. Assign IPv6 address from /32 address space of NIIF/HUNGARNET? - not very optimal since the only transit to hu primary will be NIIF/HUNGARNET - not ISP neutral - easy, no problem from point of view of NIIF/HUNGARNET 2. Assign IPv6 address space from /48 allocated to BIX (based on ripe-256 and ripe-310)? - According to the RIPE documents: "Networks assigned under this policy may not be globally routable" - which problematical since primary DNS servers should be globally reachable. 3. Allocate multiple /48 from IPv6 providers in HUNGARY to primary hu DNS server? - This can be problematical since the answers to DNS queries might be quite big. 4. Allocate /48 to primary hu DNS server that is globally routable? Are there similar to /48 from 2001:0500::/30 in RIPE region? - I think this is the cleanest solution. Can we discuss this issue on the working group or mailing lists? I saw a proposal: http://www.ripe.net/ripe/policies/proposals/2005-2.html In my opinion this can solve the problem....
