If you have the arp address of a device you can do

arp -s 192.168.1.42 00:40:63:C0:BA:E7

which would allow you on the box where you setup the static arp address to
telnet 192.168.1.42 and set the real ip address. All you have done is modify
the systems arp table/cache to set a static arp address.
