It is somewhat odd, as I get this:

$ host ntp0.dundee.ac.uk

$ nslookup ntp0.dundee.ac.uk
;; connection timed out; no servers could be reached

So ping is able to perform the name-to-IP conversion fine, but host and nslookup both fail!
Other 'normal' programs seem to perform address lookup OK (e.g. entering "www.google.com" in firefox, or even ntp if restarted later) so there is something bizarre about the network management.
