Dynamic Dns Service - NETGEAR DGN3500 User Manual

Dynamic DNS Service

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 will be, and the address can
change frequently. In this case, you can use a commercial Dynamic DNS service, which
allows you to register your domain to their IP address, and forwards traffic directed at your
domain to your frequently changing IP address.
Note:
If your ISP assigns a private WAN IP address (such as 192.168.x.x
or 10.x.x.x), the Dynamic DNS service will not work 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. You must first visit their website at
account and host name, which you configure in the wireless modem router. Then, whenever
your ISP-assigned IP address changes, your wireless modem router automatically contacts
the Dynamic DNS service provider, logs in to your account, and registers your new IP
address. If your host name is hostname, for example, you can reach your wireless modem
router at hostname.dyndns.org.
From the main menu, under Advanced, select Dynamic DNS to display the Dynamic DNS
screen.
