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.
14.11.1 Opening a Dynamic DNS Account
To be able to use the Dynamic DNS (DDNS) feature, you must first open a free DDNS
account at http://www.dyndns.org/account/create.html. When applying for an account, you
need to specify a user name and password. Have them readily available when customizing
MP-20x's DDNS support. For detailed information on DDNS, refer to
http://www.dyndns.org.
