Whats is IP address and class of IP address range of each class ?

An IP address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves as an identifier for the device within the network.

There are five classes of IP addresses, which are categorized based on the range of numbers in the first octet of the address. The classes are as follows:

1. Class A: Range of IP addresses from 1.0.0.0 to 126.255.255.255
2. Class B: Range of IP addresses from 128.0.0.0 to 191.255.255.255
3. Class C: Range of IP addresses from 192.0.0.0 to 223.255.255.255
4. Class D: Range of IP addresses from 224.0.0.0 to 239.255.255.255 (reserved for multicast addresses)
5. Class E: Range of IP addresses from 240.0.0.0 to 255.255.255.255 (reserved for experimental use)

Each class of IP address has a different range of numbers in the first octet, which determines the size of the network that can be created using that class of addresses.
