Many people use dynamic dns for different purposes. I use it to give my home machine a public presence. I choose DynDNS for my needs. Its a leader in this segment and have been around for a long time.
First, you’ll need to register for a free account at their site. Once you’ve chosen a domain name and setup your details, you’ll need a dynamic dns client to update your IP, which probably changes every time you sign on to your ISP.
I use inadyn, a free dynamic dns update client that works in linux.
The Inadyn package name is
inadyn-mt. Install inadyn using yum:
yum install inadyn-mt
Then edit the
/etc/inadyn.conf file with your details.
Then turn on the service.
service inadyn start
/var/log/messages. you should get some entires showing whether you
edited the config file properly, and the update was successful.

Once you know the client works, dont forget to turn it on permanently on startup.
chkconfig inadyn on
