13.18 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 will change accordingly to reflect the change. In this way, even though
your IP address will change often, your domain name will remain constant and accessible.
13.18.1 Opening a Dynamic DNS Account
To be able to use the DDNS feature, you must first open a free DDNS account at
http://www.dyndns.org/account/create.html.
When applying for an account, you will need to specify a user name and password. Have
them readily available when customizing the MP-202's DDNS support. For detailed
information on DDNS, refer to http://www.dyndns.org.
