No, you have misunderstood the problem.  is presumably the address of your NAT router. It's
using its own DHCP server to give you its own address as a nameserver
because it's running a DNS proxy.

My D-Link ADSL-router has a similar problem, its DNS proxy was very
unreliable  with FreeBSD, much worse than 10 second delays, many
lookups didn't resolve at all. Disabling IPv6 did help speed things
up, but didn't cure the problem entirely.

If you have a fixed location (i.e. it's not a laptop that connects
elsewhere), it's probably better and easier to avoid DHCP altogether,
since you are not getting any dynamic configuration from it. 

I setup my desktop PC like this:

ifconfig_vr0="inet  netmask"

this gives me a fixed private ip address, instead of one that depends
on what else is plugged into the router. The address is reserved in
the router.
