<p>Get the computer's public address. </p>
<p>The public address is the address of the computer from the internet point of view, i.e. something like 89.54.1.169. It is necessary for communications over the world wide web. The only way to get a public address is to ask it to a distant website; as a consequence, this function depends on both your network connection and the server, and may be very slow. You should use it as few as possible. Because this function depends on the network connection and on a distant server, you may use a time limit if you don't want your program to be possibly stuck waiting in case there is a problem; use 0 to deactivate this limit.</p>
