Hi Tim, The server does not do the resolving, instead, it is on the client computer. That means that if on one computer the client correctly resolves (actually reverse-resolves) a lot of names, and on others it doesn't, that means that the user has incorrectly configured DNS on the other client computer. Also, keep in mind that the user interface "replaces" IP addresses with names, as resolved names come in. So initially it shows only IP addresses, but then starts replacing them with DNS names as they are resolved. Some take longer than others, but after a couple of seconds you can be reasonably sure it doesn't have a DNS name.
Is the entry with the Windows hostname the same computer where you are viewing IM Flows?

One entry, in fact, seems to have the Windows hostname, rather than DNS entry! Dartware, any more detail on how this is done (or supposed to be handled?)? If Flows has not yet fully implemented DNS lookups, I'd like to third the request, please. ---------------------------------------------------- And at the further risk of going off topic, our network is organized both by hostname (reverse DNS) AND IP address (there 2nd octect tells me what kind of equipment this is, the 3rd octect tells me which site its at). Still, DNS is more informative, and you can always just not do DNS entries if you are really opposed to hostnames. :-) Tim Huffman Director of Engineering Business Only Broadband, LLC O (630) 590-6012 C (630) 340-1925 [EMAIL PROTECTED] www.bobbroadband.com > -----Original Message----- > From: [email protected] [mailto:InterMapper- > [EMAIL PROTECTED] On Behalf Of Matt Carroll > Sent: Thursday, September 11, 2008 8:50 PM > To: InterMapper Discussion > Subject: Re: [IM-Talk] InterMapper Flows > > At risk of going slightly off topic just to agree with you... ;) > > My opinion (and experience) is that systematic use of host names is a > level of sophistication - which is not to say it's rocket science - > that many network managers (of networks both large and small) never > achieve.
