14.1 DDNS Overview

14.1.1 What You Can Do in this Chapter

• Use the DDNS screen (see
domain names and their details.
• Use the DDNS Add/Edit screen (see
UAG or to edit the configuration of an existing domain name.

14.1.2 What You Need to Know

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.
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 UAG. When registration is complete, the DNS service provider gives
you a password or key. At the time of writing, the UAG 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 UAG.
After, you configure the UAG, it automatically sends updated IP addresses to the DDNS service
provider, which helps redirect traffic accordingly.
