Dear Cox High Speed Internet Customer,
In partnership with the Open DNS Resolver Project, we are identifying customers who have DNS servers as open resolvers. Your Cox IP address is listed on the report as having a DNS server as an open resolver. It is possible that this may be occurring without your knowledge.
Open DNS resolvers can be exploited and abused by criminals for DNS Cache Poisoning and Denial of Service Attacks. They allow outsiders to consume your internet bandwidth for malicious purposes. This poses a significant threat to you, other Cox customers and the Internet, as a whole. This vulnerability can also impact your quality of service.
There may be a setting within your router called "DNS Proxy" or "DNS Relay". You will want to disable this service within your router's configuration menu, if it is enabled. If you aren't sure how to check or disable this feature, you should refer to your product manual or technical support.
It is also possible that one or more computers behind your cable modem are infected with malware and are being exploited to host rogue DNS servers. Please make sure your anti-virus software is up to date and run full scans on all computer systems within your household.
If you are intentionally running a DNS server, please disable it. In addition to the aforementioned risks, Cox does not permit our residential subscribers to operate servers or Internet services to persons outside your household.
Please provide prompt attention to this matter. Continued operation of an open DNS resolver may result in temporary disruption of your internet service, should your system be exploited for a major network attack.
Could this be referring to the Subsonic settings, or is something else altogether? And if it is my Subsonic configuration with which they are taking issue, do I have a leg to stand on? Any answers you could provide would be most appreciated!
