dynamic Ip addresses

[lambs4]

Hi,
I'm creating a chat program and in the end I would like to host it. But because I'm on dial-up my IP address is always different. A solution people have suggested is to use no-ip. How do I use that?

So when a user wants to connect to my chat application they would use somename.no-ip.org instead of 123.456.789?

Yes, it's called DNS - DNS binds a name to an IP addr.

Like...

www.cprogramming.com is a DNS domain name, the IP is hidden(sort of) from ppl so the IP and computer/location can change but ppl will always be able to find it by typing in the URL.

A Dynamic Name Service is a fairly easy concept. Everytime you connect to the internet, your ip changes, as you know. What happens is this:

When you sign on, the DNS client, in this case no-ip, will assign your username and the domain you chose to your new ip. So instead of connecting to

ip.ip.ip.ip on say port 80, they would connect to

user.no-ipDomanin.com on port 80.

It gives a random set of numbers a constant set of letters. If it still doens't make sense, use it once or twice and it will.
