This protocol anomaly is a DNS message with a set of DNS pointers that form a loop. This may indicate a denial-of-service (DoS) attempt. This entry may also trigger on non-DNS traffic transiting port 53, such as Peer to Peer, Chat, Trojan Horse Backdoors or other illicit traffic.
A DNS packet with a pointer loop is a protocol anomaly which some programs may not handle gracefully.
