On the APNIC mailing list (sig-dns) a discussion has been begun to try and define the problem needing to be solved (assuming there is one). I'm not sure that the discussion should be mirrored here, but I wanted to call attention to those interested. List info - List-Id: APNIC SIG on DNS issues <sig-dns.lists.apnic.net> List-Archive: <http://www.apnic.net/mailing-lists/sig-dns/> Before spouting too much on my own here, what is the topic that needs to be discussed(on this mailing list)? ...what RIPE defines (or should define) as a problem delegation? ...a means to measure the health of the DNS delegations? ...how ccTLDs go about testing delegations? ...what responsibility a registry has in publicizing their test criteria? I know that some of the above are topics that are not what is desired, but I'm just trying to throw out some suggestions. The reason I am doing this is that there has been a recent spurt in DNS health mailing lists and it would be good if we could consolidate discussions so as not to cross-post, repost, etc. Also, the topics above have either recently appeared or were mentioned at the recent meeting. BTW - I am not saying that RIPE has a lame delegation problem. Stats I've seen are that "bad delegations" are much more rare in the RIPE region than in the ARIN region. There are possibly clear reasons for this - in the ARIN region, delegations are "cut" in the DNS without any pre-testing of servers. Also, ARIN has a lot of delegations that predate ARIN's establishment. Also - I'm shying away from using "lame delegations" based on how it is defined in the RFCs. The suggested name I threw onto the APNIC list is "unreachable zones." -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Edward Lewis +1-703-227-9854 ARIN Research Engineer Your office is *not* a reality-based sit-com TV show.
