Thank you for your email and questions. My comments are below.
Yes, but perhaps this isnt the best language. I think that the last sentence should actually be removed or at least rephrased. Perhaps we could say something like.. "as in IPv4, it is the LIRs responsibility to delegate or to maintain PTR records for its customers networks."| 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'?
If you (or the IPv6 guidelines wg) has suggestions for alternative wording please let the Secretariat know).
I have the feeling that it is not necessary to say this, since longer prefixes can of course be delegated. Perhaps it is better to say that the size of the reverse delegation by an LIR to an end site will typically be a /48, in line with the recommended minimum assignment to an end-site.| 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.
And add the above sentence to clarify.
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).
Thanks for your input. best wishes, Anne --
