UPDATE: This was an old post, but i noticed that ns1.lv.cox.net is still hijacking irc.mzima.net so i figured an update would be good to this. It doesn’t look like the irc is responding but it could be locked down to cox ips only.
Problem: Looks like various US cable companies are Hijacking DNS of well known irc servers to redirect to their own irc server in order to clean one type of drone. I believe this type of drone is the sd-bot, and its variants.
Incase you didn’t click on the drone link above, or need a better definition of what we consider drones. Drones in the IRC world are machines that have been hacked and used for flooding a user or channel, or used to cause a Denial of Service or Distributed Denial of Service against various targets across the internet.
Evidence:
Using the following dns servers:
ns1.lv.cox.net
ns1.sd.cox.net
ns1.dc.cox.net
(there are many many more dns servers but this is just a handful)
checking irc.vel.net, irc.mzima.net, and irc.dks.ca (there are others but this is broad enough) you can see that the record shows.
bash2-2.05b$ dig @ns1.dc.cox.net irc.mzima.net

Now for the real record.

You can see Cox has its own ip in the record.
also cox changes the SOA and serial: irc.mzima.net. root.irc.mzima.net. 2005072868 3600 900 86400 3600
real SOA and serial: ns1.lax01.mzima.net. dnsadmin.mzimanetworks.com. 2007083007 7200 3600 1209600 86400
so what happens when you connect to the cox ip address?

Then you get disconnected after a timeout.
