DOMAIN NAME SYSTEM SERVER

摘要

A domain name system (DNS) server is disclosed. The DNS server includes: a receiver to receive a DNS query comprising a domain name from a client device, wherein the domain name corresponds to a host server; a modifier to append a domain to an end of the domain name to create a modified domain name; and a mapping engine to compare the modified domain name to a local cache, wherein the local cache comprises a list of domain names, at least some of which are to be routed to an Internet Protocol (IP) address corresponding to an intermediate server.
