DNS servers for Vibe Communications
My modem, a CNet CAR2-804, returns DNS responses on a non-authoritative port. This causes 30 second lookup delays in Linux and timeouts in Windows 7. The workaround is to use an external DNS server instead. I set this up manually on each machine.
The settings for my machine are taken from my ISPs support page: (recorded here because I always forget where to find them)
