This module is designed to fetch your external IP address from the internet.
|
||
|
|
It is used mostly when behind a NAT.
|
||
|
|
It picks your IP randomly from a serverlist to minimize request
|
||
|
|
overhead on a single server
|
||
|
|
|
||
|
|
If you want to add or remove your server from the list contact me on github
