As the system grew this task became difficult for any one site to handle, and a new management structure was introduced to spread out the updates among many domain name registrars.Registrars today offer end-user updating to their account information, typically using a web-based form, and the registrar then pushes out update information to other DNS servers.In the initial stages of the Internet (ARPANET) addressing of hosts on the network was achieved by static translation tables that mapped hostnames to IP addresses.The tables were maintained manually in form of the host file.
The second is usually a web-based protocol, normally a single HTTP fetch with username and password which then updates some DNS records (by some unspecified method); this is commonly used for a domestic computer to register itself by a publicly-known name in order to be found by a wider group, for example as a games server or webcam.
DNS is based on a distributed database that takes some time to update globally.
When DNS was first introduced, the database was small and could be easily maintained by hand.
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.
