  to specify multiple whitelisted networks.

  Prefix(es) will be auto-registered only when remote IP address is within the specified
  range(s), except blacklist ranges.

  Default: 0.0.0.0/0 and ::/0

``-b`` or ``--blacklist``
  Blacklisted network, e.g., 192.168.2.32/30 or ::1/128.  Can be repeated multiple times
