IP Address and Classes

IP stands for Internet Protocol.

IP Address is an unique identifier given by dhcp service for a device on the network. It's used to identify particular devices, and to transfer data. There are primarily 2 types:

• IPv4 : 10.2.2.3

• IPv6: 2001:0db8:85a3:0000:0000:8a2e:0370:7334

IPv4 is a 32 bit binary number. Each number is called octet sparated by a period.

00001010 . 00000010 . 00000010 . 00000011

IPv4 Comes in 5 different classes: A, B, C, D, and E.

• Class A: 0.0.0.0 to 127.255.255.255

• Class B: 128.0.0.0 to 191.255.255.255

• Class C: 192.0.0.0 to 223.255.255.255

• Class D: 224.0.0.0 to 239.255.255.255

• Class E: 240.0.0.0 to 255.255.255.255

IPv6 uses a 128 bit address which is represented as eight groups, separated by colons, of four hexadecimal digits.
