To quote from the UNIX System Administration Handbook, 2nd ed.:
If a host is itself a name server, it should be the first host listed.
Use the actual IP address instead of the loopback address (127.0.0.1).
A bug in the BSD netwoking code can cause problems if the loopback
address is used. Each host listed must be running a recursive name
server; the resolver doesn't follow referrals.
Of course, this might have just applied to BSD 4.3, not BSD 4.4

BIND - Berkeley Internet Name Domain system. Not actually named ;-)
