When you launch your Minecraft and go into your profile by pressing the "Play" button you will be presented with a "Multiplayer" option. Click it.

From there you can put in the IP address or hostname of the server you want to play on. You'll need to find a server on the Internet. Here's a list of a few: https://web.archive.org/web/2020/http://www.minecraftworldmap.com/play
