Wireless-N 150 Router WNR1000v2 User Manual Using a 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 router contains a client that can connect to the Dynamic DNS service provided by DynDNS.org. You must first visit their website at www.dyndns.org and obtain an account and host name, which you specify in the router. Then, whenever your ISP-assigned IP address changes, your 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 router at hostname.dyndns.org. Select Dynamic DNS under Advanced in the main menu. The Dynamic DNS screen displays. Figure 4-3 To configure for a Dynamic DNS service: 1. Register for an account with one of the Dynamic DNS service providers whose names appear in the Service Provider list. For example, for DynDNS.org, select www.dynDNS.org. Customizing Your Network Settings 4-5 v1.0, November 2009

Using a Dynamic DNS Service

If your Internet Service Provider (ISP) gave you a permanently assigned IP address, you can

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.

Your router contains a client that can connect to the Dynamic DNS service provided by

DynDNS.org. You must first visit their website at

www.dyndns.org

and obtain an account and host

name, which you specify in the router. Then, whenever your ISP-assigned IP address changes,

your 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

router at hostname.dyndns.org.

Select

Dynamic DNS

under Advanced in the main menu. The Dynamic DNS screen displays.

To configure for a Dynamic DNS service:

in the

Service Provider

list. For example, for DynDNS.org, select

www.dynDNS.org

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.
