Re: [sig-policy] IPv6 Guidelines document
Dear APNIC Secretariat,
Thank you very much for drafting the IPv6 guidelines document.
I have a few questions and comments.
| 10 Requesting a reverse DNS delegation
| -------------------------------------------
|
| LIRs should maintain reverse DNS delegations for their customers'
| networks. If a network is not specifically associated with an LIR then
| the reverse DNS delegation should be maintained by APNIC. Reverse DNS
| delegations are not compulsory when an end site assigns an address to
| an individual host.
Does the last sentence mean 'it is not compulsory for an end site
to prepare PTR records for each host'?
| The minimum size of a reverse DNS delegation is /48.
Is there a special intension to specify this?
It is possible to delegate longer prefix than /48 and some
organizations may delegate such prefix in their internal network.
As described at Sec 5, this guidelines document is for ISPs (not for
end sites), so it is Ok from that viewpoint, but if previous sentence
describes an end site (my question above), I think it's better to
clarify the condition for /48 minimum delegation (e.g. from ISP to
end sites).
