I have not objection to the creation of sink.arpa, but I will repeat comments I made on the NANOG list that there are ways of accomplishing the same thing which do not require the creation of this registry. One example method would be to create MX records which point to 257.in-addr.arpa; this address is already guaranteed not to have any resource records associated with it by the structure of the reverse tree. The tricky bit here is, in fact, not the creation of the record which is guaranteed not to have a resource record, it is generating good practices for when this would get used and how. Can I point a CNAME to sink.arpa, for example? How do I manage the expiration in that case, given that the negative existence of sink.arpa is declared to be infinite? The MX case may very well be useful, and I repeat that I have no objection. But the IESG may want to consider whether referral to a WG for either the BCP aspects in relation to mail or the DNS itself is warranted. regards, Ted Hardie On Mon, Dec 21, 2009 at 10:40 AM, The IESG <iesg-secretary@xxxxxxxx> wrote: > The IESG has received a request from an individual submitter to consider > the following document: > > - 'The Eternal Non-Existence of SINK.ARPA (and other stories) ' > <draft-jabley-sink-arpa-02.txt> as a BCP > > The IESG plans to make a decision in the next few weeks, and solicits > final comments on this action.
