Use ARP to assign ip address 150 150 Roderick Derks

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
