The Domain Name System brought a method of distributing the same address information automatically online through recursive queries to remote databases configured for each network, or domain.Even this DNS facility still used static lookup tables at each participating node.Dynamic IP addresses present a problem if the customer wants to provide a service to other users on the Internet, such as a web service.
Due to the distributed nature of the DNS systems and its registrars, updates to the global DNS system may take hours to distribute.
Thus DNS is only suitable for services that do not change their IP address very often, as is the case for most large services like Wikipedia or Google.
The communication between the user's equipment and the provider is not standardized, although a few standard web-based methods of updating have emerged over time.
The standardized method of dynamically updating domain name server records is prescribed by RFC 2136, commonly known as dynamic DNS update.
The first is "dynamic DNS updating" which refers to systems that are used to update traditional DNS records without manual editing.
