  • Method and router to permit or block internet protocol (IP) connectivity based on originating domain name server (DNS) requests
    Patent number: 10686753
    Abstract: A router and method for validating Domain Name Service (DNS) queries which can include sending them upstream. Internet Protocol Enforcement (IPE) is included into the router to allow passage of Transmission Communication Protocol (TCP) and User Datagram Protocol (UDP) traffic through a compatible gateway only when the destination IP address was the result of a prior validated DNS query still in its TTL (time to live) period. IP packets that did not originate with a DNS query can be blocked by default, for example.
