This chapter discusses how to configure your ZyXEL Device to use Dynamic DNS.

19.1 Overview

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 applications such
as NetMeeting and CU-SeeMe). 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.
First of all, you need to have registered a dynamic DNS account with
www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP
server that would still like to have a domain name. The Dynamic DNS service
provider will give you a password or key.

19.1.1 What You Can Do in the DDNS Screen

Use the Dynamic DNS screen
configure the DDNS settings on the ZyXEL Device.

19.1.2 What You Need To Know About DDNS

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.
If you have a private WAN IP address, then you cannot use Dynamic DNS.
