A downloadable database of Australian postal codes, collated from a variety of public sources on the Internet

Today I found myself writing code to review the validity of the many, err, dozens of domain names that I oversee.
I wanted to incorporate this into my personal intranet site, written in ASP.
NET using the 4.
The task was to validate whether a domain name was correctly delegated, with valid A records pointing at one or more of my web servers, or externally hosted servers.
Using the system.
net assembly to query a domain record is relatively trivial, but using it to query external name server delegation proved to be somewhat cumbersome, so I decided to simply use Window’s built in nslookup tool, available since Windows 2000 (and maybe earlier!).
