Configuring Dynamic DNS (If Needed) 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 will not be routed on the Internet. If your network has a permanently assigned (static or fixed) 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 will 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 an extension to its domain, and resolves DNS requests for the resulting FQDN to your frequently-changing IP address. For rollover mode, you will need a fully qualified domain name (FQDN) to implement features such as exposed hosts and virtual private networks regardless of whether you have a fixed or dynamic IP address.

Configuring Dynamic DNS (If Needed)
If your network has a permanently assigned (static or fixed) 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 will 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 an extension to its domain,
and resolves DNS requests for the resulting FQDN to your frequently-changing IP address.
For rollover mode, you will need a fully qualified domain name (FQDN) to implement features
such as exposed hosts and virtual private networks regardless of whether you have a fixed or
dynamic IP address.
Note:
At this point in the configuration process, you should now be connected to the
Internet.
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 will not be routed
on the Internet.
