IP blacklist monitoring

Watch an IP or an IPv4 network against the common DNS blacklists and get told when it gets listed.

  • Choose which blacklists to check and how many hits count as down.
  • Works on a single address or a whole IPv4 network, checked address by address.
  • Runs at most every 15 minutes, so the public blacklists are not hammered.
  • Available on Business.
