Dns updating

Below the root, Internet resources are organized into a hierarchy of domains, administered by the respective registrars and domain name holders.A DNS name server is a server that stores the DNS records, such as address (A, AAAA) records, name server (NS) records, and mail exchanger (MX) records for a domain name (see also List of DNS record types) and responds with answers to queries against its database.

It translates an often humanly meaningful, text-based identifier to a system-internal, often numeric identification or addressing component.

This service is performed by the server in response to a service protocol request.

An example of a name server is the server component of the Domain Name System (DNS), one of the two principal namespaces of the Internet.

In addition, many home-networking routers implement caching resolvers to improve efficiency in the local network.
