14.11 Dynamic DNS

The Dynamic DNS (DDNS) service enables you to alias a dynamic IP address to a static
hostname, allowing your computer to be more easily accessible from various locations on
the Internet. Typically, when you connect to the Internet, your service provider assigns an
unused IP address from a pool of IP addresses, and this address is used only for the
duration of a specific connection. Dynamically assigning addresses extends the usable
pool of available IP addresses, whilst maintaining a constant domain name.
When using the DDNS service, each time the IP address provided by your ISP changes,
the DNS database changes accordingly to reflect the change. In this way, even though
your IP address changes often, your domain name remains constant and accessible.
