# Convert arp.dat to ethers format

# - sort on timestamp, newest first
# - discard entries without simple hostnames
# - discard all but first occurance of each ethernet address
# - discard entires with raw ip addresses for simple names
# - remove ip address and timestamp fields
# - append "-ip" to hosts with decnet address too
# - append "-old", "-old1", etc. as necessary
# - sort
