Global IP or IPv4

hi guys having problem which one will i use.. if i use my global ip when im entering the game i cant see anything just background no choosing of server but when i change it to my IPv4 all of the ip's needed to be setup the game running smooth and no problem.. it is possible that my frends can connect to my server? and one more thing how can i link my website to others so they can download my game client and enter my webshop? thanks for who will answer.. Godbless!!

Global IP you need to open ports on your router for you to be able to make it online and if you can't use that just use hamachia but if you do your friend will haft to download it and connect your hamachia. And then use your client.

And for your website same rules apply.
