Ever Wondered about this Internet Protocol? Then You are at the right place to know the actual things in a quite informal way. If you have ever tried setting up a router at your home/office, you might notice that all the network addresses are more similar, such as 192.168.72.21 and 192.168.l0.1. But what might be the reason for using these particular IP Address instead of other !!? Without wasting much of our time let me dig out with the actual basics. All internet-enabled devices don’t have the unique Internet Protocol(IP). If there is one we might fall for the shortage of those addresses.

Why exactly do we use 192.168.72.21 for small private networks:
Long Ago, back in 1996, the team of IETF(Internet Engineering Tak Force) sorted out some things after their hours of discussion and one of them is “They thought to give away only a range of IPV4 Address for internal purposes” i.e IP’S between a particular range is given to the devices within closed networks such that this range of IPs is not available for Public Usage.
What are Public and Private Addresses?
Public addresses are issued by your internet service provider. Your router assigns an internal IP address to each of the devices connected to the network so that we can identify the devices connected to a closed group. For Example, If 3 systems are connected to your Home Router it assigns an internal address to each of the devices just to identify them.
What is IPV4 Address?
IPV4 is an internet protocol address with a range of numerical labels assigned to the internet-enabled devices connected to a closed network for IP Communication. It is described in 32 bit and is displayed as 6 plots.
Note: The below data is used for Private networks only.
Finally, IETF teamed with IANA(Internet Assigned Numbers Authority) and reserved three range of IP addresses for the private networks.
- 10.0.0.0 – 10.255.255.255 (Class A)
- 172.16.00 – 172.31.255.255 (Class B)
- 192.168.0.0 – 192.168.255.255 (Class C)
You have to choose one of the ranges from the above depending on how large your network is !! In detail,
- Class A can be given to a network that needs 16,777,216 IP addresses.
- Class B can be given to a network that needs 1,048,576 IPs
- Class C can be given to a network that needs 65,536 IPs
So Which Class does our private home network needs? Hope we don’t even connect some 50-100 devices to a single private home network.Low Class=Less Technical Problems
So Our Home-based private networks (Routers)Falls under class C i.e 192.168.0.0 to 192.168.255.255 which also means you can connect 254 devices to one Home Private connection. So this was the reason for assigning
You can any class of these private networks addresses according to your need. There is no limit and some rules for your Addresses. If you need to connect someone\’s lakh internet-enabled devices within a private network(Assume you need a private network for a small company)you can simply create with class B. There are the ranges created just for our use But based on our needs. You have the freedom to choose the class as per your requirements.
Things we do with 192.168.72.21
If you are reading this on an internet connection through a private network(Router), simply follow the steps to know what you can do with the IP.
- You can change the security settings of your Home Router.
- If you are using a router based on this IP Address, You can get access to your Admin part of your home network where you have a chance to change a lot of options such as DNS, Proxy, Network management, and what not!
- You can access WLAN settings, DHCP Client settings as well.
