I've got a local network, my Linksys/Cisco WRT54G w/DD-WRT blew up this morning, I swapped it w/ a spare dlink DI-624 I had lying around. It was a pretty stock configuration, all I did was change the local network to 192.168.1.1 (from the dlink default of 192.168.0.1) and enabled WPA2-PSK with the passkey that I already had setup on the rest of the network.
So here's the odd part. I ping most of the local hosts (about a half dozen) by hostname and get a normal response. One of them, I ping and I get a response from some computer somewhere out on the internet (208.68.143.50).

I have never seen anything like this before.
Any thoughts?
