I'm not aware of any such document, but agree it would be useful.

Yes, the IETF docs I've seen are focused on operational practices related
to DNS as it interacts with technologies such as IPv6 and DNSSEC:

http://tools.ietf.org/html/rfc4472   Operational Considerations and Issues
with IPv6 DNS
http://tools.ietf.org/html/rfc6781   DNSSEC Operational Practices, Version
http://tools.ietf.org/html/draft-howard-isp-ip6rdns-06  Reverse DNS in

Interestingly, there are efforts underway within a number of the network
operator groups to help document best current operational practices. My
colleague Jan Zorz has been traveling around speaking with a good number
of *NOGs on this particular issue (and is in Zambia at AfriNOG right now)
and we've started trying to document the BCOP activity happening in
various groups here:


Working with one of those groups might be a way to move a document
forward.  Or creating a repository of DNS-related BCOPs might be a great
role that DNS-OARC could play.
