DDNS
11.1 DDNS Overview
Dynamic DNS (DDNS) services let you use a domain name with a dynamic IP address.
11.1.1 What You Can Do in this Chapter
• Use the
DDNS
screen (see
) to view a list of the configured DDNS
domain names and their details.
• Use the
DDNS Add/Edit
screen (see
) to add a domain name to the
USG 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 USG. When registration is complete, the DNS service provider gives
you a password or key. At the time of writing, the USG 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 USG.
After you configure the USG, it automatically sends updated IP addresses to the DDNS service
provider, which helps redirect traffic accordingly.
