4.3 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 DNS-like address (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 DNS name. The Dynamic
DNS service provider will give you a password or key.
4.3.1 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.
If you have a private WAN IP address, then you cannot use Dynamic DNS.
