13.1.2 What You Need to Know About DDNS

DNS maps a domain name to a corresponding IP address and vice versa. Similarly, dynamic
DNS maps a domain name to a dynamic IP address. As a result, anyone can use the domain
name to contact you (in NetMeeting, CU-SeeMe, etc.) or to access your FTP server or Web
site, regardless of the current IP address.
You must have a public WAN IP address to use Dynamic DNS.
You must set up a dynamic DNS account with a supported DNS service provider before you
can use Dynamic DNS services with the ZyWALL. When registration is complete, the DNS
service provider gives you a password or key. At the time of writing, the ZyWALL supports
the following DNS service providers. See the listed websites for details about the DNS
services offered by each.
