DNS problems?

I don't seem to be able to perform any DNS lookups other than via Plusnet's own DNS servers.
For example, the following Linux commands work OK with Plusnet's DNS servers:
dig @212.159.13.49 www.google.co.uk
dig @212.159.13.50 www.google.co.uk
However the following Linux commands all hang with Google Public DNS servers and OpenDNS servers:
dig @8.8.8.8 www.google.co.uk
dig @8.8.4.4 www.google.co.uk
dig @208.67.222.222 www.google.co.uk
dig @208.67.220.220 www.google.co.uk

It is almost as though Plusnet is blocking DNS requests to non-Plusnet DNS servers.
Is it something to do with Plusnet SafeGuard? Its FAQ does mention DNS.
Should I raise a support ticket?

At a guess this should disable other DNS servers, to prevent circumvention.

Safeguard uses a different pair of DNS resolvers.
What router are you using? Is the Plusnet server Firewall enabled (although I don't think the latter should make any difference).

To answer your questions, my router is a Netgear DG834G, and my Broadband Firewall is off.

Did you try any sites other than Google when the problem was evident?

If it was just Google-hosted stuff then the difference might have been explained by the fact that we have Google caches on our network.
Aside from that, I'm out of ideas. Shout up if it happens again.
