An IP address is the network address of the device. A network underlying layer that is responsible for addressing and routing is the network layer. It is layer three as per the OSI model. On the internet that uses TCP/IP, Internet Protocol(IP) implements the network layer. So the address over a network is known as an IP address.

What is my public IP address?

When you browse a website or access a server, you might be connecting via a LAN or could connect directly with the Internet Service Provider(IP). But most of the time, it’s over LAN. So there are two types of IP addresses involved: a private IP  that your computer has and another public IP address that your ISP assigns.

The public IP address is similar to the postal address of your home. The addresses are managed by IANA, which allocates the addresses and assigns them to the service providers of various countries. An ISP provider gets the ranges and uses them with the end users.

An end-user could be a company, a shop, or an individual user at home. The public IP address is mapped on the modem/router that terminates the line from the provider. On another side, the model connects to the LAN.

How can I check my Public IP address?

You can not check the public IP address from your local machine unless you have access to the router. In that case, you can use this portal. You can see your public IP address and other details at the start.

Why do we need to know what my public IP is?

While using the internet, one never cares about the public Ip assigned to the router. But if you need to access a client company’s system for ssh or telnet, then it is important.

For security reasons, the client will allow your IP on the firewall to grant access. In that case, you need to find what public IP you are using and share it will the client.

What is my private IP address?

The private IP address is the network address (e.g., 192.168.1.34) that your computer ethernet card has to configure to connect to a LAN. It could be a dynamic or static address. 
There should be a DHCP server running over the LAN for dynamic IP. Mostly the router runs a DHCP server too. The user configures static using a graphical interface or command-line interface.

On Linux, there are files for each network interface in /etc/sysconfig/network-scripts/ . A sample (e.g. ifcfg-enp0s3) will look like following

TYPE="Ethernet"
 PROXY_METHOD="none"
 BROWSER_ONLY="no"
 BOOTPROTO="dhcp"
 DEFROUTE="yes"
 IPV4_FAILURE_FATAL="no"
 IPV6INIT="yes"
 IPV6_AUTOCONF="yes"
 IPV6_DEFROUTE="yes"
 IPV6_FAILURE_FATAL="no"
 IPV6_ADDR_GEN_MODE="stable-privacy"
 NAME="enp0s3"
 UUID="cea511f7-d869-4c87-8721-cfd517cc1334"
 DEVICE="enp0s3"
 ONBOOT="yes"
 IPADDR="192.168.1.195"
 PREFIX="24"
 GATEWAY="192.168.1.1"
 IPV6_PRIVACY="no"

On Windows, you can configure it step by step.

  • Open the folder Control Panel\Network and Internet\Network Connections
  • Right-click on the network interface and select properties.
  • Choose to click on Internet Protocol Version 4.
  • Fill in the details of the private IP address.
