In this environment, DNS namespaces mirror the Active Directory forests and domains used by an organization.

Network hosts and services are configured with DNS names so that they can be located in the network, and they are also configured with DNS servers that resolve the names of Active Directory domain controllers.

"Dynamic DNS or DDNS is a method of updating, in real time, a Domain Name System (DNS) to point to a changing IP address on the Internet.

This is used to provide a persistent domain name for a resource that may change location on the network." Wikipedia, Premium Members can choose up to 20 names in their Forwarded Ports page, accessible from the left tabs of their "Client Area".

As the number of hosts on the Internet grew, the traffic generated by the update process increased, as well as the size of the HOSTS file.

DNS originated in the early days of the Internet when the Internet was a small network established by the United States Department of Defense for research purposes.

Domain Name System (DNS) is one of the industry-standard suite of protocols that comprise TCP/IP, and together the DNS Client and DNS Server provide computer name-to-IP address mapping name resolution services to computers and users.

In Windows Server 2016, DNS is a server role that you can install by using Server Manager or Windows Power Shell commands.

The Domain Name System introduced in 1984 became this new system.

With DNS, the host names reside in a database that can be distributed among multiple servers, decreasing the load on any one server and providing the ability to administer this naming system on a per-partition basis.For example: if you want to host a game server, you can communicate to the players the DNS name and freely switch Air VPN servers. If you change VPN server, one hour may be needed before other users can resolve correctly your domain name.A longer time might be necessary: some public DNS (for example Google DNS) sometimes ignore TTL in their caching system.When any of the principal Active Directory operations is performed, such as authentication, updating, or searching, computers use DNS to locate Active Directory domain controllers.
