Sorry,
I know it was late when I posted this but I should have said that I had tried Whois etc.
You get the reply " This domain cannot be registered because it contravenes the Nominet UK
naming rules. The reason is:
the domain name contains too many parts."
Because it's mysubdomain. atmyisp.co.uk if you see what I mean.
I can look up my isp ok .
But what I'm worried about is my privacy is not compromised.
if the sub domain can be looked up in some way.
