System message error updating dns nameserver not registered
Many providers offer commercial or free Dynamic DNS service for this scenario.
The automatic reconfiguration is generally implemented in the user's router or computer, which runs software to update the DDNS service.
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.
IP addresses, once assigned to a particular host, rarely changed and the mechanism was initially sufficient.
In addition, this helped conserve the address space available, since not all devices might be actively used at all times and addresses could be assigned as needed.Smaller services, however, are generally much more likely to move from host to host over shorter periods of time.Servers being run on certain types of Internet service provider, cable modems in particular, are likely to change their IP address over very short periods of time, on the order of days or hours.Dynamic DNS (DDNS or Dyn DNS) is a method of automatically updating a name server in the Domain Name System (DNS), often in real time, with the active DDNS configuration of its configured hostnames, addresses or other information.The term is used to describe two different concepts.
End users of Internet access receive an allocation of IP addresses, often only a single address, by their Internet service provider. static), or may change from time to time, a situation called dynamic.
