tool for finding undelegated children in your DNS

[Victoria Risk]

I have been told this is a very poor description of the problem.

What I am concerned about is, how people with a sort of lazy zone file can assess the potential impact of QNAME minimization on their ability to answer for all of their zones.

I have gotten two suggestions off list:
- I would use named-checkzone to print the zone with all owner names printed out and then use text processing tools
- “dig ds -f list-of-zones”, Those that return NXDOMAIN are likely missing NS records.

Any other ideas?
Has anyone done this kind of housekeeping on their own zones?
