3.7.1 Personal Domain Name (DDNS)
Typically, when you connect to the Internet, your service provider assigns an unused IP address from a pool of IP
addresses. This type of address, called a dynamic IP address, is only assigned to you for the duration of the
connection. Each time you connect to the Internet, a different IP address is assigned to you. Dynamically assigning
addresses extends the usable pool of available IP addresses. However, since in this configuration the computers have
no fixed IP addresses, the access to those computers from the Internet with a specific IP address is not possible.
A Dynamic DNS (DDNS) service enables you to alias a dynamic IP address to a static hostname. When you use a DDNS
service, each time the IP address provided by your ISP changes, the DNS database is updated to reflect the change.
Regardless of the IP address assigned to your computer, it will have a constant domain name. This way, even though
your IP address may change often, your domain name will remain constant and your computer will be accessible.
Note: In order to use the W40 DDNS feature, you must first obtain a DDNS account. 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. Then create the free DNS host and activate it. Please have them readily available when you activate the
W40 DDNS support.
 To activate W40 DDNS support:
1. Navigate to Home  Personal Domain Name. The Personal Domain Name overview screen appears.
