I can't reproduce this anymore, so no packet data. I guess it's a moot point now. But I was just intrigued by that last ping, where I received data back but it came from multiple IP addresses.

I was doing some testing on my home network and was having some betwork issues. I would start a ping /t to my router and it would reply for a few second and then time out for a few seconds. In my testing, I noticed that the "Reply From" IP address changed mid-ping. In the following copy/paste, please note the following: Network setup: Desktop <ConnectsTo> Router Router is 10.1.1.1 Desktop is 10.1.1.12 The Desktop is running Vista Ultimate x86 The Router is a Linksys WRT54G I have 2 more PCs connected directly to the router Below is the copy/paste from the command prompt. It starts when I was running "ping 10.1.1.1 /t". I stopped it when I saw "Destination host unreachable" from 10.1.1.12 (the host compter running these ping commands).

Has anyone seen anything like this before? Now, I did just move this PC from another room so could it have been some leftover ARP stuff or something? I was having significant issues with my network yesterday and I was thinking that this might be related. The other PCs were able to ping the router and each other reliably. But this one desktop (10.1.1.12) was having significant issues. Any thoughts? Thanks, Frank
