Patent abstract
Technology related to processing network packets with returnable values is disclosed. In one example, a method includes intercepting a Domain Name System (DNS) request including returnable request values in respective request packet fields. A hash function can be used to characterize or modify the intercepted returnable request values. The intercepted DNS request can be forwarded to a DNS server. A DNS response including returnable response values in respective response packet fields can be received. The returnable response values and the hash function can be used to determine whether the DNS response is legitimate. A legitimate DNS response can be forwarded to a client.
