You would have heard that IP addresses help uniquely identify a device in internet - if that is the case how is that a lot of us have 192.168.1.2, 192.168.1.3 etc as our IP addresses? Won't they conflict with each other?
Let's find that out using some simple activities when you are behind a wifi router.
Activity #1: What's your IP (in terminal)?
A private IP address is specifically assigned to a device in a controlled network and is not easily accessible on the wide internet. With a private IP address, all devices assigned that particular private IP will be able to communicate with each other. How Private IP Address Works? A private IP address is a non-internet facing IP address on an internal network. Network devices, such as routers, provide private IP addresses using network address translation (NAT). Private IP addresses are not able to be tracked by the public. Access your private IP address in Windows 8/8.1/10. My IP address information shows your location; city, region, country, ISP and location on a map. Many proxy servers, VPNs, and Tor exit nodes give themselves away. IP address lookup, location, proxy detection, email tracing, IP hiding tips, blacklist check, speed test, and forums.
Find your system's IP address when you are connected to wifi router. You can do it using ipconfig command in windows or ifconfig command in Linux/Mac.
You can see that the interface name is wlp2s0 which denotes my wifi router and the IP address I got is 192.168.1.163.
1. If you have one more laptop in your house connected to the same router, can it have the same IP address?
2. If you go to your friend's home and connect to her wifi router, is there a possibility to get the same IP address?
Activity #2: What's your IP (in browser)?
Will the IPs change depending upon where you find it from? Go to google.com and type what's my ip

Google just returned my IP address as 184.108.40.206.
Who is right? Is it my terminal or Google as they seem to return different addresses.
Activity #3: What's your mobile's IP (in browser)?
Connect your mobile to your wifi network (not 4G) and then go to google.com and type the same query what's my ip
Response from Google will be the same on your mobile browser as well - 220.127.116.11 in my case.
- What you get from Google (18.104.22.168) is your public IP which is common across any device that is connected to your wifi router. It is allocated by your Internet Service Provider (ISP).
- What you get from the terminal (192.168.1.163) is your private IP which is unique to every single device connected to your wifi router.
|Private IP||Public IP|
|Unique only in your network which includes all devices connected to your router||Unique in the world - otherwise you are going to run into conflicts|
|Assigned to you by your home wifi router using DHCP protocol||Assigned to you by your ISP like BSNL, Airtel, AT&T, T-Mobile|
|You can change what IP addresses to assign to the|
devices by configuring your wifi router.
For example, you can ask your router to assign addresses
starting with 192.168.1.x or 192.168.2.x
or anything else for that matter
|You do not have direct control over what IP addresses you are assigned|
|Cannot be reached from outside world||Can be reached from outside world|
Activity #4: Who can talk to your computer?
Though you can access the entire internet from your computer, the reverse is not true. For you to connect to a system in internet, you need its IP address and the IP address should be public. When you are behind a wifi router, you only have a private IP address. This means to the internet, your system doesn't exist :)
Ask your friend to ping 192.168.1.163 from his house. He will not be able to reach your system.

Activity #5: Changing public IPs
Shutdown your modem and reboot it after 5 minutes (not your wifi router).
What Is My Private Ip Address
Your modem is the device that is connected to the ISP either through fiber or other means. For some of you, your wifi router and modem may be the same device.
Are you getting the same public IP or a different one? There is a chance that you might get a different IP address from your ISP because your public IP is dynamically allocated.
If you are hosting a site at your own, then this may not work as you need a single IP address for everyone in the world to reach you consistently. You don't change your name everyday - do you ;-)?

To overcome this, you can pay extra to your ISP and get a Static public IP address. As the name denotes, it doesn't change across reboots for your connection. In other words, if you type what's my ip in Google every single day, you will get the same response. You can read more about static IPs here - https://whatismyipaddress.com/dynamic-static
