	Are you talking about the ntlworld.com domain?  If so, then I 
don't see any such TTL:

	Indeed, having thrown doc, dnswalk, and DNS Expert Professional 
1.6 at this domain, this is the first time I recall in a very, very 
long time that someone has posted with problems about a domain, but 
where the DNS debugging tools I have don't really find anything 
(okay, so they complain that they can't do a zone transfer, but 
that's understandable).

	If the question is with regards to any other domain, then share 
with us the real domain name in question, and we might be able to 
help.
