I have installed Nginx webserver on my system. I just need to know the IP adress of the server which am running. I have Googled many times but I didn't get a good answer.
If you are on Windows, use the command line and enter
If on Linux, enter
In case you get lost or forget the cmd command use this link:
The WAN address is your External IP
The LAN address is your internal IP on that particular machine.
P.S. - for the foreseeable future look for IPv4, IPv6 is estimated not to take over IPv4 for a long time.
Hope this helps :)
