In addition, many home networking routers implement caching resolvers to improve efficiency in the local network.Google Public DNS is a freely provided closed-source DNS (Domain Name System) service announced on 3 December 2009,as part of Google's, self-proclaimed, effort to make the web faster. That server provides the answer to the question, or definitively says it can't be answered, and the caching resolver then returns this response to the client that asked the question.The authority, resolving and caching functions can all be present in a DNS server implementation, but this is not required: a DNS server can implement any one of these functions alone, without implementing the others.Internet service providers typically provide caching resolvers for their customers. It continues until it reaches the authoritative server for the zone that contains the queried domain name. To do this the name server queries each authoritative name server in turn, starting from the DNS root zone.
