# this blacklist of DCC clients is used by the public DCC servers.  The
#   public DCC servers should only be used by small sites that qualify
#   for the free license on the DCC source.
#   See http://www.dcc-servers.net/dcc/ concerning DCC
#
#   This list contains IP addresses and blocks of addresses of DCC clients
#   that persistently cause problems such as sending more than 100,000
#   requests per day to the public DCC servers.  This list causes the public
#   DCC servers to ignore requests even before checking the automatic
#   rate-limiting mechanisms.
#
#   This blacklist has no direct effect on email.

#   Operators of public DCC servers can use the user names and passwords that
#   they use to see the DCC server status web pages to see the consolidated
#   lists of the busiest clients of the public DCC servers at
