Well DynDNS
is coming from Dynamic DNS
Dynamic DNS is when you have Domain Name but you don't have
same IP address all the time.
So some people with Dynamic IP address, register on this site
and VOLA them Domain Name is active where-ever they connect to
internet, no meter that them IP Address is different all the time.
Back to the topic - I can't see this to be useful for the Tittle of this post.....
