Hi,
Hi,
1) Count how many delegated domains there are (Names with NS records)
Mind your $ORIGIN and check the number of NS record owners.
2) Extract the above Names - so I can look for changes (Added/Deleted names)
I suspect that deltas; add / change / delete, will likely be outside of the scope of what bind will provide unless you crank up logging and parse it or behave as an incremental zone transfer client.
3) find out how many unique names have DS records (I can DIG I suppose)
Mind your $ORIGIN and check the number of DS record owners.
I'd also like to spot broken stuff (named-checkzone ?)
How are you getting your zone data? Is it a zone transfer (AXFR / IXFR)? Or do you have raw zone files?
One hindrance is that journal files are present - so it is not just the zone file but the zone.jnl file as well.
Check out the "-clean" flag to the "sync" command for rndc.
The primary purpose is to pull in data into an (ICANN requested) African DNS Observatory.
It sounds like you might be better off extracting data for multiple zones / (sub)domains therein from DNS and storing it in some format, likely a database, that will then be easier to process.
