Since we're on the topic of dnsmasq and OpenDNS, here's a nice way
to get rid of that annoying behavior where a non-existent hostname
resolves to OpenDNS's web server.
In a browser, you'd see a page that says "you entered an address that
does not exist, maybe you meant BLAH". But this really stinks for
anything other than a browser (SSH, ping, traceroute, IMAP, etc).
Put this in dnsmasq.conf and you'll get proper NXDOMAIN responses for
hostnames that should not resolve.
bogus-nxdomain=208.69.32.132
If you're running Tomato on a router, you should be able to paste that
line into the config box for additional dnsmasq settings.
