Chapter 21 DNS

"If you have a private WAN IP address, then you cannot use Dynamic DNS.

21.10.2 High Availability

A DNS server maps a domain name to a port's IP address. If that WAN port loses its connection, high availability allows the router to substitute another port's IP address for the domain name mapping.
