Objective

The Domain Name System (DNS) is a feature that maps Internet domain names to IP addresses. Dynamic DNS (DDNS) is a feature that allows devices to be located through domain names even if the IP address of the device has changed. The CVR100W router uses DDNS through a web-based DDNS accounts; 3322.org and oray.org. If the WAN IP address of the CVR100W changes, the DDNS feature notifies the DDNS server of the change. The DDNS server then updates the configuration to include the new WAN IP address. This is useful if the WAN IP address of the router often changes. A DDNS account must be created on one of the provided websites to utilize the DDNS feature on the CVR100W. This article explains how to configure Dynamic DNS on the CVR100W VPN Router.
