Zone stats

[Mark Elkins]

Hi,

I'm writing some software to be able to read information from a Zone 
file. I am a legally authorised Secondary Authoritative Nameserver for a 
number of domains or rather zone files, eg. EDU.ZA (and others). Is 
there an easy way to:-

1) Count how many delegated domains there are (Names with NS records)

2) Extract the above Names - so I can look for changes (Added/Deleted names)

3) find out how many unique names have DS records (I can DIG I suppose)

I'd also like to spot broken stuff (named-checkzone ?)

So the zones (such as EDU.ZA) contain the domain name of the entity 
(whois.edu.za) along with the Nameserver records and in this case, a DS 
record. e.g... "whois.edu.za" looks like....

whois                              NS        control.vweb.co.za.
                                    NS        secdns1.posix.co.za.
                                    NS        secdns2.posix.co.za.
                                    NS        secdns3.posix.co.za.
                                    DS        27300 13 2 
8ED21DB407F6AC3E6EA757AE566953C1BBADD8B652BE4C7C0744B1D7 9DF42894
                                    DS        17837 13 2 
36FD5B19450B672988AE507FB7D2F948ED1E889546C6E16554C7EAF9 CE9C3FEA

One hindrance is that journal files are present - so it is not just the 
zone file but the zone.jnl file as well.

Some African ccTLDs have everything in one zone e.g. their COM, EDU, GOV 
- etc. In South Africa, these are all separate zones, making life 
somewhat easier.

I'd hate to re-invent software that already exists.

The primary purpose is to pull in data into an (ICANN requested) African 
DNS Observatory.
