Dynamic DNS
Internet service providers (ISPs) assign numbers called IP addresses t\
o identify each 
Internet account. Most ISPs use dynamically assigned IP addresses. This means that the IP 
address can change at any time. You can use the IP address to access your network 
remotely, but most people don’t know what their IP addresses are or when this\
 number 
changes.
To make it easier to connect, you can get a free account with a Dynamic D\
NS service that  lets you use a domain name to access your home network. 
 To use this account, you must set 
up the modem router to use Dynamic DNS. Then the modem router notifies the Dynamic 
DNS service provider whenever its IP address changes. When you access yo\
ur Dynamic 
DNS account, the service finds the current IP address of your home netwo\
rk and 
automatically connects you. 
If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic 
DNS service does not work because private addresses are not routed on th\
e Internet.
