Is it to do with G4?
I have three pismo all recognised by name by my BT router while my G4 has always been 'Unknown Host'.
I have tried complete shutdown of router and all the macs to no effect.
The G4 name is 'G4S', ie no spaces (another member mooted that).

In the list of devices connected to my router and assigned IP
addresses, everything shows up as I would expect, except a G4 MDD
(10.4.11) and an 800 MHz G4 ILamp (10.2.8).

For those two machines the router displays something like unknown_<MAC
address> without the <> for the Device Name.

I tried entering the machine names into the optional DHCP name box
(forgot exactly what it's called) in the System Prefs/Networking/
Ethernet/DHCP window, but that had no effect, other than, when I
clicked "Apply Now" it caused the computer to release its current IP
and obtain a new one.

My old System 9.1 machine shows up in the router list under its
machine  name, even.   It's just these two OSX Macs that don't.

Now that I'm at work and where I can test it, the only thing I can
think of is that the two Macs in question have space characters in
their machine names.  Do routers reject machine names if they have
spaces in them, or is something else going on here?   If the latter,
what?  Is there some way to get the machine name to show up under
Device Name on the router, instead of the MAC address?

The router in question is one of AT&T's HGV3600 modem/router
gateways.   I just switched to U-verse.
