I'll take a look at that, thanks.

I also have more info...

My router is stupid. apparently it sends to the dhcp clients the
nameserver address you enter into the dhcp configs, but it appends
its own LAN address to it so the clients get both:

that is a discussion of a similar router from the same mfg as mine, and
it behaves the same way.

You can see this directly if you have a windows system, run "ipconfig /renew"
then "ipconfig /all" and you'll see both addresses listed as DNS.

Now, does that have anything to do with my Centos box which is
manually configured? I can't see how, but it makes me wonder.
