We have been here before. The ENUM name space has comparable properties to ip6.arpa: lots of labels, "irregular" delegation points and sparse population. Some ENUM applications and use cases had a need to find the closest encloser too. So a long time ago, I helped write up something similar for the ENUM WG -- http://tools.ietf.org/html/draft-ietf-enum-void-02 -- and was told I was a naughty boy. It was apparently a Very Bad Thing to treat data from the Authority Section as an answer from the DNS: resolving servers could do this, but nothing else apparently. I suspect Mark's draft may have been killed because of that too. FWIW there were other religious issues which meant that ENUM draft ended up going nowhere. _______________________________________________ DNSOP mailing list [email protected] https://www.ietf.org/mailman/listinfo/dnsop
