Converting int to strings?

How do you do it?
I have this little piece of code but I dont know how to convert it.
Do I have to use another variable?

var IP		: int;
var PORT	: int;

function ResetIP() {
    MasterServer.ipAddress = (IP);
    MasterServer.port = (PORT);
}
Debug.Log(MasterServer.ipAddress);

intValue = 3;
intString = intValue.ToString();

That’s not relevant since Unity doesn’t use web Javascript. You can use ToString, or simple concatenation if there’s another string involved. (i.e., ‘var foo = “x” + 5;’ makes the ‘5’ be implicitly converted to a string without having to specify ToString.)
