DDNS stands for Dynamic DNS. It is a way of automatically updating a name server in the Domain Name System.

This is useful in the case of web resources which may change IP addresses on a frequent basis (daily or even hourly). The DNS records are updated by a local router or server whenever the IP address of the resource changes.

This is usually not an issue for typical web hosting plans, as web hosting providers use blocks of static IP addresses. However, it is an expected feature of many internet-connected devices, since they are dynamically assigned a new IP address every time they are restarted.

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.
