Banned IP range / addresses

  • Comments 2

The functionalities of the server I administer include web sites, web forums, web blogs and a mail server.

I have banned the following IP ranges / addresses from accessing my mail server. If a single IP tries to spam me, I ban the entire network to which the IP belongs to.

Quite draconian, but I have no love for spammers and those supporting them.

    My name is Sheryl Daniel and I am currently the abuse administrator for Dialtone I have discovered that our IP 69.0.0.0 is listed within your blacklist, please let us know who the offender is or was, so that we can clear up this issue. Dialtone/Interland works with the anti-spam community to clean up our network and will continue to do so.

    Thank you.

  • We also find the most port scanning and other
    exploits coming from the ip address range of
    68.0.0.0 - to 69.0.0.0 .

    While the criminals abusing these servers may
    be third party, many webmasters are blacklisting
    this range to better serve real customers.

    With 65,535 ports on every machine running tcp/ip,
    we find security much easier by blocking 120,000
    (local+remote) ports that we do not use. This
    has provided much faster service on the ports we
    do. No need for port scanners, just close 95%
    of all ports and the other 5% perform much better.
    Simple but effective.
