Thank you to everyone who has replied. Charter have got back to me and are investigating this now. Appreciate everyone's fast responses!

We are currently having this issue with Charter Communications, and were also having the same issue with the University of Tennessee, however they have since corrected the issue. I have left multiple voicemail messages with Charter's listed ARIN contact, however we have had no responses or success. I would appreciate it if anyone on, or off-list can provide any contact details, or forward this email on to someone at Charter who can have their bogon filters checked, and 223.0.0.0/8 removed. I would also appreciate any other providers who are on this list and are still employing Bogon filtering, to double check your lists, and remove 223.0.0.0/8 as APNIC has been allocating IP addresses from this subnet since October 2010. http://mailman.apnic.net/mailing-lists/apops/archive/2010/11/msg00001.html Best Regards, Greg, on behalf of Desura Pty Ltd
