Editing Dynamic DNS (section)

==== DDNS for Internet access devices ====
DDNS providers offer a software [[Client (computing)|client]] program that automates the discovery and registration of the client system's public IP addresses. The client program is executed on a computer or device in the private network. It connects to the DDNS provider's systems with a unique login name; the provider uses the name to link the discovered public IP address of the home network with a hostname in the domain name system. Depending on the provider, the hostname is registered within a domain owned by the provider, or within the customer's own domain name. These services can function by a number of mechanisms. Often they use an [[HTTP]] service request since even restrictive environments usually allow HTTP service. Most providers have an API similar to a first provider DynDNS (Dyn.com) so it's often called DynDNS2.

Many home networking [[Residential gateway|modem/routers]] include client applications in their [[firmware]], compatible with a variety of DDNS providers.
