CombiStack Networking is toolkit for gathering networking information like Public IP, Private IP, DNS settings, resolving IP to hostname, DNS resolving, etc.
Modules are logicaly sorted so, that you look in a folder which data you have and then, there are modules that can get something from that data.
If you have no data, just look in a folder with name of what data you need.
For example, if you have ip and need hostname, you can look inside /ip/ and find host.js there.
If you need to get your public ip for example, you can look inside /ip/ and public.js is there.
