Warwick Broadband have an IP blacklist problem. We almost cured it last month
and now it is very much back. We need everyone to change their email
credentials and run antivirus protection.
We believe the blacklisting is caused by SPAM being sent from one or more
subscriber computers. But, it may be IP spoofing, using our customer’s email
credentials from a remote site. Fixing this requires running antivirus software
on your computers and keeping the protection current.
If this is happening remotely (meaning: not on our network) the fix is for
folks to change their email passwords. That way a remote server can’t
successfully pretend to be one of us.
Studying this today added another element to ponder: are websites blocking our
IPs because they see too many connections coming from it?
Options we are considering include implementation of carrier class network
address translation where customers are assigned to a unique port range which
means we can track down offenders with some snooping; using public IP4
addresses; or implementing public IP6 with support IP4). The advantage of the
public IP address use will be that only the “offender” will be impacted by
blacklisting.
