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 works because private addresses are not routed on the Internet. Your wireless modem router contains a client that can connect to the Dynamic DNS service provided by DynDNS.org.

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 works because private addresses are not routed on the Internet.
Your wireless modem router contains a client that can connect to the Dynamic DNS service
