  • SYSTEMS AND METHODS FOR DETECTING PRESELECTED QUERY TYPE WITHIN A DNS QUERY
    Publication number: 20120047571
    Abstract: In some embodiments, a non-transitory processor-readable medium storing code representing instructions to cause a processor to perform a process includes code to determine whether an IPv4 packet is associated with a Domain Name System (DNS) query based on an IPv4 header of the IPv4 packet. If the IPv4 packet is a DNS query packet, the non-transitory processor-readable medium includes code to determine whether the IPv4 packet has a preselected query type based on a payload of the IPv4 packet. If the IPv4 packet is a DNS query packet and has the preselected query type, the non-transitory processor-readable medium includes code to send a signal to block transmission of the IPv4 packet. In some embodiments, the preselected query type has a DNS record type value of 28.
