3.4.3.6.1 Configuring DDNS
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.
To use the DDNS feature, you must first obtain a DDNS account. For example, you can
open a free account at http://www.dyndns.com/account/create.html . When applying for an
account, you will need to specify a user name and password.
Use the DDNS feature to define different static host names for each of your WAN
connections. Moreover, you can define more than one static host name for each WAN
connection, by simply repeating the following procedure for the same connection.
