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. -- "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." - Benjamin Franklin, Historical Review of Pennsylvania, 1759.
