What is DynDNS:
As you know any domain should be pointed to an IP in order to be seen in browsers. If you don’t have a connection to the internet with static IP (cable, DSL, etc.), then it becomes tedious to set an A record for your domain every time your IP changes. Dynamic DNS is a feature that will allow you to point a domain name to any IP and the changes are almost immediate.
For example, you have a server at home and host a website on your computer. But you don’t have a static IP, that is the IP changes each time you reconnect to the Internet, you can setup Dynamic DNS for the domain.

## For those using Redhat style rc files and using daemon-mode:
cp sample-etc_rc.d_init.d_ddclient /etc/rc.d/init.d/ddclient
## enable automatic startup when booting
/sbin/chkconfig –add ddclient
## start the first time by hand
## If you are not using daemon-mode, configure cron and dhcp or ppp
## as described below.
use=web, web=checkip.dyndns.com/, web-skip=’IP Address’
# I need to update for my subdomain
ddclient -daemon=0 -debug -verbose -noquiet
