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.
