Thanks for the reponse Walt.

My Mac's do use TCP/IP. However, raw TCP/IP itself cannot resolve host
names. Just as PC's use NetBIOS over TCP/IP (NetBT) for their naming
convention, Mac's use TCP/IP packets tunneled through an AppleTalk capsule
for theirs. So while it may be possible to ping a PC client from another PC
client and receive the host name in the return packet, this isn't possible
when pinging from a PC or *nix client to a Mac, and apparently no one
bothered to include name resolution in the Mac ping utilities that are
currently out there.

This could be helpful. Do you know what package its a part of?

I am assuming from this that either every machine on your network has a
static IP address or that your DHCP server makes entries and updates your
DNS table. Unfortunately I am running DHCP on Windows and DNS on AIX (I
inherited the setup), so I can't use your type of system. Would be cool if I
could though.
