Discover IP address from MAC

Hi

I have a MAC address but no IP address. This is for a little label printer that I've just plugged into my network. The network is DHCP enabled and I've checked both DHCP allocation tables for the MAC but it doesn't show. I've made a reservation for the MAC but it doesn't take it. I've pinged the subnet and tried "arp-a" on each DHCP server but the MAC is not in the output list.

I need a suggestion for how to continue - any ideas?
Thanks

Sounds like the lable printer has been assigned a static IP address.  Look at the documentation to reset it to the factory default.

Otherwise post the model/brand info here so we can research further.

Is there an option on your printer to specify DHCP? It's possible that it's set to static and not making the request.

Check which ports are open to the outside world. Helps make sure that your firewall rules are working as intended.

Maybe it is running Appletalk or NetBEUI or even DECnet, then it won't have an IP address.

There is no switch to set it to DHCP, and no reset button.

If it does have a static IP assigned, it will be from our old subnet (a 192..x.x.x range) but the office moved recently and the subnet changed to a 10.x.x.x range

Connect a PC to it with a crossover cable and change the PC's address to the old range, then scan the subnet. Alternatively reset it to defaults - default IP address 192.168.254.254 or 198.102.102.254 according to http://www.zebra.com/id/zebra/na/en/documentlibrary/manuals/en/ZebraNet_PrintServer_II_Users_Guide.File.tmp/45537L-004rA_Final.pdf

If you don't have a cross over cable.  Connect it to another switch with your computer and give your computer an IP address in the same subnet.  Then connect to the device and change's it IP address, or set it to use DHCP.

If it has a static IP it will never look for a nother one.

Thanks dude, that worked a treat. I put the PC NIC on the same segment as the old office LAN and pinged the broadcast IP and up it popped in the arp table.
