An error that is returned quickly isn't a problem - a timeout of many
seconds is a problem. How long do the failing responses - and for your
IP addresses and 127.0.0.1 take?
The cleanest approach is to run a local nameserver that is primary for
your local domain (even if it is not official) and your local network
ranges and caches for everything else.
