Instead of using colons(:) between each set of numbers, use dots(.) in your IP address. For an example, you can write 121:121:121:121:7777 as 121.121.121.121:7777. But remember the port number for an IP address is separated using a colon(:), so I hope you can easily see it there in that example. The "server.me:7777" has an IP address assigned to it. But for most people it's hard to remember an IP address exactly the way it is, so instead of numbers here we can use words.
