Hi,
Thanks very much for that document. It is very useful for the community.
I have only 2 comments concerning Appendix A:
Thanks for your comments.
1) Among the 39 mentioned name servers, why are there duplicates (same names with the same addresses, see for example d.dns.jp (3 times) or ns.nic.ir (2 times) ?
Oops. Seems like I forgot a uniq(1). The result with respect to drops still stands, but the 39 figure is actually less.
2) As far as I know, the IPv4-mapped IPv6 addresses are irrelevant in this context (see *.dotdm.net et *.netdns.com), do these name servers have regular (2001 or 3ffe) IPv6 addresses ?
We queried the auth nameservers for those. They only report mapped addresses, no global addresses. Why are these mapped addresses irrelevant in this context? They show up in the additional section.
On the other hand, I would like to share with you the follwing document which focuses on DNS response size calculation (from root servers) and name compression for TLDs with IPv6 taken into account. A part of the document sections deal with the general case, so they can apply to any TLD. The remaining sections contain calculations for .FR and may be easily extended to any other TLD. If you have any comment, suggestion or correction, don't hesitate to send them to: ipv6tech@nic.fr.
Please find the document at:
I will have a look at it. rvdp
