If you do something like "dig google.com @205.152.37.23", do you get a
quick response?  Do it at least twice, the first response will be slow,
subsequent ones will work from a cache.

Likewise, try against the secondary DNS server address.

I think you're fixating on bind-config.  It doesn't play a role in your
hosts file, nor activating ethernet interfaces.

DHCP just configures your side of the network with the data that the
DHCP server says to use (as you supplied above).  If there's a wonky
DHCP server configuration, you might get told to use a DNS server that's
incorrect, or not even get some of the information that you need.

So, one of them is most likely the culprit, not BIND.  I thought they
were used for something like wireless?  Or, at least for switching
network configurations around for people who use multiple different
networks, but not simultaneously (e.g. work, home, internet cafes).  If
you're not doing either, you can probably do without them.  I don't have
them, but then I have a modem/router between me and the ISP.

Only if you have a LAN using those addresses.  Or, if you want to fake
things as if you had, giving your machine an interface with a consistent
address.

Don't send private replies to my address, the mailbox is ignored.
I read messages from the public lists.
