We have introduced a web filter at the company where I work (Im the IT Manager).
The web filter allows exceptions. But its so secure (not a bad thing!!) that I need to add all subdomains to the exceptions listing.
So if I wanted to allow http://news.bbc.co.uk
I need to add that and not just http://bbc.co.uk
The web filter wont allow wildcards.
So my questions is, is there an easy way to retrieve the DNS listing for bbc.co.uk that will give me all the subdomains of the parent domain name?
