CHAPTER 12
Dynamic DNS
12.1 Overview
Dynamic DNS (DDNS) services let you use a domain name with a dynamic IP
address.
12.2 What You Can Do in the DDNS Screen
Use the Dynamic DNS screen (Section 12.4 on page 128) to enable DDNS and
configure the DDNS settings on the NBG-417N.
12.3 What You Need To Know About DDNS
Dynamic DNS allows you to update your current dynamic IP address with one or
many dynamic DNS services so that anyone can contact you (in NetMeeting, CU-
SeeMe, etc.). You can also access your FTP server or Web site on your own
computer using a domain name (for instance myhost.dhs.org, where myhost is a
name of your choice) that will never change instead of using an IP address that
changes each time you reconnect. Your friends or relatives will always be able to
call you even if they don't know your IP address.
12.3.1 DynDNS Wildcard
Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be
aliased to the same IP address as yourhost.dyndns.org. This feature is useful if
you want to be able to use, for example, www.yourhost.dyndns.org and still reach
your hostname.
Note: If you have a private WAN IP address, then you cannot use Dynamic DNS. You
must have a public WAN IP address.
