# Read a receivedIPdb database on stdin, making an update to stdout by
# verifying that each record in the database is in one of the black
# lists.
#
# Requires Edward S. Marshall's rblcheck(1) program to validate each of
# the IP addresses.
#
# Usage:
#
#     receivedIP.validate < receivedIP.db > temp
#     cp temp receivedIP.db
#
# where receivedIP.db is a receivedIPdb database.
#
# Note: For Class A, Class B, and Class C, database records, only two IP
# addresses are verified; 0 and 255.
