<p>Hi,</p>
<p>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:-</p>
<p>1) Count how many delegated domains there are (Names with NS
records)</p>
<p>2) Extract the above Names - so I can look for changes
(Added/Deleted names)<br>
</p>
<p>3) find out how many unique names have DS records (I can DIG I
suppose)<br>
</p>
<p>I'd also like to spot broken stuff (named-checkzone ?)<br>
</p>
<p>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....</p>
<p>whois NS control.vweb.co.za.<br>
NS secdns1.posix.co.za.<br>
NS secdns2.posix.co.za.<br>
NS secdns3.posix.co.za.<br>

</p>
<p>One hindrance is that journal files are present - so it is not
just the zone file but the zone.jnl file as well.</p>
<p>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.<br>
</p>
<p>I'd hate to re-invent software that already exists.</p>
<p>The primary purpose is to pull in data into an (ICANN requested)
African DNS Observatory.<br>
