[acm-tf] How about a DNS-based interface?

Hi all, one question I'd like to put next Tuesday (if I'll be able to connect) is if it would be feasible/convenient to have the IP-address to point-of-contact database available via DNS, with central delegation similar to in-addr.arpa, but not going beyond RIRs. RIRs would populate TXT records with the email address, copying the data present on the whois database. I think this would definitely boost the usability of that data, as it (1) leverages a powerful cache mechanism, and (2) provides a well-known interface, uniform across all RIRs. The global DNS should be named something like _poc.iana.org, or similar global name. Thus, we should seek more sponsors. But do we ourselves like the idea? For IPv6 the problem is more difficult but less urgent. The increased difficulty lays in the cache blasting that would result if clients queried a lot of addresses. There is a proposal[JL] to avoid that by forcing clients to discover the granularity of an IPv6 allocation and then query the correct range. That doubles the number of queries but increases the likelihood of cache hits.
