:I don't believe you show up in the list since it seems to be generated via DHCP requests. Unless the DI-624 is doing some kind of Reverse ARP (RARP), it won't be able to figure out a name for your statically assigned box.
Also you said it's able to ping, nslookups, and traceroute's, so you're fine.
It seems that given enough time it comes up and is recognized. I've given up on this version and went back to the B11 versions. It seems it too has 'unknown' as the name of the machine.
