12.1.2 What You Need To Know

The following terms and concepts may help as you read through this chapter.
What is DDNS?
DDNS, or 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.
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.
