Dhcp updating dns records

IP addresses, once assigned to a particular host, rarely changed and the mechanism was initially sufficient.However, the rapid growth of the Internet and the proliferation of personal computers in the workplace and in homes created the substantial burden for administrators of keeping track of assigned IP addresses and managing their address space.Dynamic DNS is a system that addresses the problem of rapid updates.The term is used in two ways, which, while technically similar, have very different purposes and user populations.Many providers offer commercial or free Dynamic DNS service for this scenario.

The first implementations of dynamic DNS fulfilled this purpose: Host computers gained the feature to notify their respective DNS server of the address they had received from a DHCP server or through self-configuration.This, however, broke the end-to-end principle of Internet architecture and methods were required to allow private networks, with frequently changing external IP addresses, to discover their public address and insert it into the Domain Name System in order to participate in Internet communications properly.Today, numerous providers, called Dynamic DNS service providers, offer such technology and services on the Internet.This protocol-based DNS update method was documented and standardized in IETF publication RFC 2136 in 1997 and has become a standard part of the DNS protocol (see also nsupdate program).The explosive growth and proliferation of the Internet into homes brought a growing shortage of available IP addresses.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.DHCP became an important tool for ISPs as well to manage their address spaces for connecting home and small-business end-users with a single IP address each by implementing network address translation (NAT) at the customer-premises router.The private network behind these routers uses address space set aside for these purposes (RFC 1918), masqueraded by the NAT device.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.
