OK. Fair enough. My main point, from a Linux perspective, was that as its so trivial to set up a caching nameserver, (indeed XP has DNS caching by default) is it worth doing the same thing on Linux,
given that
1)Im not overly impressed with NTLs proxies and infrastructure at the moment - so I was wondering if the DNS is up to scratch. (I've seen NTL's DNS mentioned a lot in these forums though I havent poured over it in detail)
2) some DNS servers seem to take ages to update regardless of TTL. Which was what I was getting at regarding my earlier statement that it may be better to have your own local one, properly configured..

Yes I do have a router with DNS set up, but earlier in the thread I mentioned I suspect this may simply be passthrough rather than caching.
