Know your public and private IP addresses

You might have used ifconfig command on your linux terminal to know different network configurations of your system. 

ifconfig command shows hardware address(HWaddr) and network address(inet addr) for Ethernet or your wifi connection. 

ifconfig command don’t show your public IP address(if public and private are different). For that purpose, you can simply type in google search : what is my ip address, it will show your public IP address. 

On linux terminal, you can use following commands to know your IP addresses: 

Public IP :

curl ifconfig.me
      or 
curl ipinfo.io/ip
