8.5 Personal Domain Name (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 ad-
dress 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 do-
main name will remain constant and accessible.
8.5.1 Opening a Dynamic DNS Account
In order to use the DDNS feature, you must first obtain a DDNS account. For ex-
ample, 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 pass-
word. Please have them readily available when customizing Watson's DDNS sup-
port.
8.5.2 Using Dynamic DNS
Use the DDNS feature to define a static host name for your WAN connection.
Moreover, you can define more than one static host name for your WAN connec-
tion, by simply repeating the following procedure.
1. Access this feature either from the 'DDNS' tab under the 'Services' screen, or by
clicking its icon in the 'Advanced' screen. The 'Dynamic DNS' connections
screen appears. This screen displays a table that will present the different con-
nections and their DDNS aliases.
