Dynamic DNS a method of KEEPING a domain name linked to a changing IP address as not all computers use static IP addresses. Typically, when a user connects to the Internet, the user’s ISP assigns an unused IP address from a pool of IP addresses, and this address is used only for the DURATION of that specific connection. This method of dynamically assigning addresses EXTENDS the usable pool of available IP addresses. A dynamic DNS service provider uses a special program that runs on the user’s computer, contacting the DNS service each time the IP address provided by the ISP CHANGES and subsequently UPDATING the DNS database to reflect the change in IP address.
