Why IP addresses are divided into classes?

IP addresses are divided into five classes that are identified by the value of the first octet (the first decimal number). The system of IP address classes was developed for the purpose of Internet IP addresses assignment. The classes created were based on the network size. For large networks with many devices.

Why are IP addresses 4 parts?

All computers on the same network share the same network ID. Each computer (sometimes called a “network interface”) has its own unique host ID. The four IP address parts do NOT have to be divided equally—it’s not always the case that two parts make up the network ID and two address parts make up the host ID.

Why did the format of IP addresses change?

That’s because the IP address of “your” computer doesn’t belong to your computer—it belongs to the network you’re connected to. Your computer is just borrowing it for a while. That’s why you’d have a different IP address at a coffee shop than the IP address you’d have at a hotel on the corner.

What is the purpose of IP address Mcq?

The IP address is a group of numbers that identify user system on the network.

What is the format of IP address version 4?

IP (version 4) addresses are 32-bit integers that can be expressed in hexadecimal notation. The more common format, known as dotted quad or dotted decimal, is x.x.x.x, where each x can be any value between 0 and 255. For example, 192.0. 2.146 is a valid IPv4 address.

Why are there different classes of networks?

Classes A, B, and C are used the most often by different networks. Subnet classes are made unique by the number of bits their IP addresses have dedicated to a network and the number of bits dedicated to hosts. Classes can be identified by the number in the first octet of their address.

What do the octets in an IP address mean?

Each of the decimal numbers in an IP address is called an octet. The term octet is just a vendor-neutral term instead of byte. So, for an IP address of 168.1. 1.1, the first octet is 168, the second octet is 1, and so on. The range of decimal numbers numbers in each octet is between 0 and 255, inclusive.

Why is my IP address different from my IPv4?

If there is any box at all in between your computer and your ISP, your computer will probably have a different IP. The reason is that there is a finite number of IPs in the world, so there has to be some way of conserving them. That way is NAT, or Network Address Translation.

Does IP address change with format?

The short answer is that for home users the IP is allocated by the service provider from a pool of IPs which are available to them, hence the IP you get can only be changed if you disconnect and reconnect to the service provider. But the new IP will still be from the IP pool of the service provider.
