Internet/Intranet web site visibility

[ByzantianX]

I'm totally new in this area. I run a small domain and I've installed IIS, defined the default web site, associated it with the public IP address, started it, but it still can not be seen from outside, just from the domain. I really don't know what the problem might be (one more time, I'm totally new in this issue). Please, help me with some advice, it's quite urgent! Thank you in advance!

You must contact your Internet Service Provider.

I should add that I suppose there is nothing to do with the DNS because when I type the address in the browser, I see the IP resolution was correct meaning I can see the exact IP address of the computer which runs the IIS. What else could be a problem? Please, help me!
