P-2024 Support Notes

WAN IP Address field.

Using Dynamic DNS (DDNS)

1. What is DDNS?

A DNS (Domain Name Service) server stores the mappings of IP address and domain names. For example,

when users enters a web site address (the domain name), the DNS server automatically maps the web site

address to a public IP address and redirects the request to the intended web server.

Without DNS, users have to enter the IP address of the web server in order to access the web sites. This is very

inconvenient and not user-friendly as users have to remember the IP addresses of the web sites.
