3.10 Applications
Below shows the menu items for Applications.
3.10.1 Dynamic DNS
The ISP often provides you with a dynamic IP address when you connect to the Internet via
your ISP. It means that the public IP address assigned to your router changes each time you
access the Internet. The Dynamic DNS feature lets you assign a domain name to a dynamic
WAN IP address. It allows the router to update its online WAN IP address mappings on the
specified Dynamic DNS server. Once the router is online, you will be able to use the
registered domain name to access the router or internal virtual servers from the Internet. It is
particularly helpful if you host a web server, FTP server, or other server behind the router.
Before you use the Dynamic DNS feature, you have to apply for free DDNS service to the
DDNS service providers. The router provides up to three accounts from three different DDNS
service providers. Basically, Vigor routers are compatible with the DDNS services supplied by
most popular DDNS service providers such as
www.dyndns.org, www.no-ip.com,
www.dtdns.com, www.changeip.com, www.dynamic- nameserver.com.
You should visit
their websites to register your own domain name for the router.

WAN IP

function can detect the public IP used by the NAT router
and use the detected IP address for DDNS update.

WAN IP
