What is IP Address?

An IP address is a number that uniquely identifies a computer or other device on a local or wide area network. As the name suggests, IP stands for “Internet Protocol,” which defines how information can be transmitted via the internet or a local network.

What does “192” mean in an IP addresses and What is it?

There were five kinds of IP addresses considered useful when IP was designed, mostly depending on the number of computers in the network. All machines on a network were also supposed to be publicly accessible from any Internet location. You had to register the address of a new network if you wanted one. All computers on your network could communicate with each other even though no one else had access to their IPs.

Class A networks are capable of hosting up to 16,777,214 devices. Its IP address ranges from 0 to 127, although 127 is reserved for use by the local loopback interface, which is a waste of address space. It’s only 127.0.0.1 that’s ever been utilized.

65,534 computers can be connected to a Class B network at once. Starting at 128 to 191, it has an IP address.

A maximum of 254 machines can be connected to a Class C network. If you’re running a small business or a home network, this should enough. A number between 192 and 223 is assigned to it as its IP address.

In multicast, Class D (224–239) is the preferred channel, whereas Class E (240–254) is set aside for private usage.

Those classes became problematic when the Internet grew in popularity. Internet computers are significantly less common than computers on private networks. There were no more addresses available, despite our best efforts to redefine the classes.

This resulted in the creation of a private network address:

Class A: Addresses that begin with ten or more characters.

Any address that begins with 172 and the second digit is 16–31 is in the middle.

Addresses with 192.168 as the first octetAny communication destined for a private network address will be dropped by all routers. For this reason, it’s a completely private matter. The Internet will never see anything you send on your local network. Everything from the Internet will not be forwarded to your local network.

It’s only natural that you’d want to communicate with the Internet. As a result, your router performs Network Address Translation (NAT). A single IP address is assigned to your router on the Internet. This is how your router starts up the connection to a server in the world and then rewrites the IP address to the local network address of your computer when you receive a response from that server.

If the router receives a message from the Internet that it has not been instructed to expect, it will delete it. In addition, you’ll have specified which computer on your network is in charge of handling the issue.

Since everyone has a mobile phone, tablet, or e-reader, 254 is still a sufficient number of addresses for our local network. Because of this, the majority of our PCs have IP addresses that begin with 192.168. Even on a modest home network, you’ll run into the other private network addresses from time to time. It all relies on how your Internet service provider (ISP) has configured your router.
