RBLs (Realtime Blackhole Lists)

There are several RBLs around on the Internet. But which one should I use?

This was the question I was asking when I started to use this lists. So here is what you have to look for. You should get a mix of different kinds of RBLs. This mix should contain at least one list of the following categories.

  • Dialup list (List of dsl, cable, dhcp and dialup lines with dynamically assigned IPs)
  • Open Proxy list (List of IP addresses with open proxy ports)
  • Open Relay list (List of mail server with a open relay)
  • Zombie list (List of IP ranges which are stolen from there rightful owners)

This mix should give you a good result.
