Odd DNS/DHCP behavior

[Alejandro 'Lanjoe9' Valenzuela]

Hello everyone, I've got a computer with FreeBSD 4.9 and it's connected 
vía LAN, to a gate2wire broadband módem/router/etc
The computer configures itself correctly vía the DHCP server inside the 
modem, and everything seems to work fine, but I get these odd messages 
and sometimes it can't resolve names until I try several times. It isn't 
much of a problem, but I'd like to know what it means..
(btw, the machine's name is "angel" (it wasn't my idea :P) and the 
domain is the modem's default: 2wire.net. The modem itself is accessible 
at gateway.2wire.net from inside the LAN).
