If you install a new device, that has no ip assigned to it, but you have the mac address of this device, you can use arp and ping to assign a temporary ip address:
1) Assign ARP/IP
Windows:
> arp –s 192.168.1.123 00-aa-cc-c6-09
Linux:
# arp –i eth0 –vs 192.168.100.124 00:0E:35:1F:91:F5
2) Ping it
A “normal” ping will not work as expected here… you need to ping it with a packet-size of 113:
Windows:
> ping 192.168.1.123 –l 113
Linux:
# ping 192.168.1.124 –s 113

Exactly what I was looking for, an example of the use of ARP. I have looked at lots of sites that tell you how it works etc but without giving an example of an ARP command. Thank you very much for a very concise piece of information. Rgds, Peter Jones.
