Those are reasonable values to use.  Some commentary:

1. It's best if you can get this data from the server, e.g. during
your PPP negotiation (our termservers will offer it).  

2. If you can't get it from the server, it's better to use the RFC1918
address you hade (192.168.37.186).  The reason these approaches are
better is that they are more portable; if we have to renumber over the
weekend due to an unplanned disappearance of our existing address space
(and our vendor, Verio, did exactly that to us three or four years ago),
these solutions will still work, while if you use the numbers from the
WHOIS, you may need to renumber if we do.

3. U of O lets us (and several other local ISPs) use phloem as a secondary
DNS server.  This may change in the future.

4. EFN nameservers do not respond to ICMP, so pinging them will not tell
you that they are up.  Fire off dig or nslookup at them to see if they
are offering name service instead.
