Recently when logging in to one of our server's through SSH, we've been getting errors from our server stating: "reverse mapping checking getaddrinfo for c-xxx-xxx-xxx-xxx.hsd1.ca.comcast.net failed - POSSIBLE BREAKIN ATTEMPT!" we did some checking and noticed Comcast isn't providing an A record for our hostmask..
