Why can't the UBRs do DNS?

Fair enough. Do you mean you're using an external (i.e not your), non NTL proxy on another port then I assume? If not, how have you managed to defeat the infernal NTL proxies?? AFAIK any proxy behind them, even though it's operating inwards on, say, port 8080, would still be making requests for webpages on the regular port 80 and so having to route through the NTL ones.

That's a non existant problem. The nature of DNS is that it updates itself, there are thousands (or more) of DNS servers around the world. It would make sense (esp after the recent problems) for each of the main router centres to have it's own set of dns servers (like they already have their own proxy servers). That would make a loss of service due to ddos much less likely (or localised). Each proxy server could have it's local area dns server as it's primary, and another area as it's secondary.
