Dynamic DNS

If your Internet service provider (ISP) gave you a permanently assigned IP address, you can 
register a domain name and have that name linked with your IP address by public Domain 
Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP 
address, you do not know in advance what your IP address is, and the address can change 
frequently. In this case, you can use a commercial Dynamic DNS service. This type of service 
lets you register your domain to their IP address and forwards traffic directed at your domain 
to your frequently changing IP address.

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 the Internet.
