Dns records updating
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.

If you have multiple resources that perform the same function, for example, web servers or email servers, and you want Amazon Route 53 to route traffic only to the resources that are healthy, you can configure DNS failover by associating health checks with your resource record sets.

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.
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.
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.
