Dynamic DNS (DDNS), solves the problem of ever-changing residential IP addresses by associating your address with a consistent domain name without the need to buy a pricey static IP.

Dynamic DNS (DDNS or DynDNS) is a mechanism by which the name server in the Domain Name System (DNS) is automatically updated with the custom domain name and the ever-changing IP addresses. The DNS method is helpful in the case of dynamic IP addresses, where the IP address is mapped to a custom domain that changes frequently. However, in the case of a static IP address mapped to a custom domain, DDNS is not required. In general, a dynamic IP address is provided to residential or small business users. Big enterprises generally use static IP with their domain names.

Such resources are typically a Web server, Webcam or a PC for remote control operation.

Cable and DSL providers frequently change the IP address of their customer's service, which makes it impossible to access the network from the outside world without knowing what the IP address is at any given moment. DDNS client software resides in a router, Webcam or PC. When it detects that the IP address of the cable or DSL modem has changed

Dynamic DNS is a system for allowing an Internet domain name (something.com) to be assigned to a dynamic (one that changes and is not always the same) IP address. Since the dynamic IP address changes, Dynamic DNS makes it possible for other computers on the Internet to establish connections to that machine without needing to know the actual IP address.
