Device or to edit the configuration of an existing domain name.

11.1.2 What You Need to Know

DNS maps a domain name to a corresponding IP address and vice versa. Similarly, Dynamic DNS (DDNS)
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 (dynamic) IP address.
Note: 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 Zyxel Device. When registration is complete, the DNS service provider
gives you a password or key. At the time of writing, the Zyxel Device supports the following DNS service
providers. See the listed websites for details about the DNS services offered by each.

Note: Record your DDNS account's user name, password, and domain name to use to
configure the Zyxel Device.
After you configure the Zyxel Device, it automatically sends updated IP addresses to the DDNS service
provider, which helps redirect traffic accordingly.
