Delete arp entry from Linux Howto

arp -a
syst (192.168.1.122) at 21:96:43:3a:62:a2 [ether] on eth0

arp -d 192.168.1.122

If you get an error do:

arp -d 192.168.1.122 -i eth0

Sometimes the arp cache just won't clear either, some say it should automatically but there are cases where the above doesn't work.  I believe it may be that some network applications are keeping the entry alive but this is just a guess.
