Chapter 12 Dynamic DNS Setup
Dynamic DNS
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.
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.

12.1.2 What You Need To Know
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.
