Using a Dynamic DNS Service
If your network has 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 will allow you to register your domain to their IP address, and will
forward traffic directed at your domain to your frequently-changing IP address.
The router contains a client that can connect to many popular dynamic DNS services. You can
select one of these services and obtain an account with them. Then, whenever your ISP-assigned
IP address changes, your router will automatically contact your dynamic DNS service provider,
log in to your account, and register your new IP address.
Tip: If the computer is already present on your network, you can copy its MAC
address from the Attached Devices menu and paste it here.
Note: The reserved address is not assigned until the next time the computer contacts
the router's DHCP server. Reboot the computer or access its IP configuration
and force a DHCP release and renew.
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.
