Janice, That makes sense, and you are right - the windows hostname I saw was my own computer, and another in my same LAN.
One question I do have, however, is that DNS resolution doesn't seem to resolve all the time. For example, I've got a window open right now, and I'm looking at an IP in the list under name (63.250.224.115), but when I open a command prompt and do a reverse lookup, I DO get a hostname (nitrogen.b1.fe2-12.chi.bobbroadband.com). This seems to be happening for several IPs. Any ideas?
