In case it's not too late, please find below my remarks and suggestions. It's up to the authors to take all or part of it into account. First, I have some general comments: 1) I would recommend to use RFC3330 addresses for example IPv4 addresses. That's to say, within: 192.0.2/24 2) It would be a good idea (and also helpful by the way for administrators) to give examples of Name Servers supporting IPv6 transport (numbering within 2001:db8::/32, RFC 3849) In that case, all illustrations with IPv4 addersses would be completed by IPv6 addresses, when needed. 3) I think that it would be better to choose an NS list for example.com zone, such that not all of them be inside the zone itself For example: example.com. IN NS master.example.com. IN NS slave.example.net. and later "slave.example.org" (for the replacement). Attached below are my comments and suggestions (with '^' for locating the context and "==>" for my text). For readers only interested in the "diffs" a diff file is also attached. Mohsen.
