Odd - thats nothing like the right address - in fact thats a 
leeds.ac.uk address so I guess you have just pasted the address of your 
name server?

Not really... although RH6.1 boxes have this utterly stupid demon that 
caches name lookups for maximum embarrassing effect and doesn't honour 
TTLs.

I have just realised, having looked carefully, that the lug.org.uk 
domain has its 2 main name servers giving out different (but both 
authoritative) answers.  This is just a bit broken but will hopefully 
be fixed soonish.
