What Are The Different Classes Of IP Addresses?

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 Class C was created for the numerous networks with the small number of hosts..

What are the 2 types of IP address?

‘IP’ stands for ‘Internet Protocol’. There are two versions of IP that currently coexist in the global Internet: IP version 4 (IPv4) and IP version 6 (IPv6). IP addresses are made up of binary values and drive the routing of all data over the Internet. IPv4 addresses are 32 bits long, and IPv6 addresses 128 bits long.

What is class A IP range?

x.x.x only. The IP range 127. x.x.x is reserved for loopback IP addresses. The default subnet mask for Class A IP address is 255.0. 0.0 which implies that Class A addressing can have 126 networks (27-2) and 16777214 hosts (224-2).

Can police trace IP?

Usually, the IP address is enough to trace the connection back to the ISP (Internet Service Provider). Generally, ISPs will work with law enforcement in cased of known fraud or theft. They usually require a warrant, but that is usually not difficult for law enforcement to get.

What are the 4 parts of an IP address called?

IPv4 addresses are usually represented in dot-decimal notation, consisting of four decimal numbers, each ranging from 0 to 255, separated by dots, e.g., 172.16. 254.1. Each part represents a group of 8 bits (an octet) of the address.

What are the 3 major classes of an IP network?

Currently there are three classes of TCP/IP networks. Each class uses the 32-bit IP address space differently, providing more or fewer bits for the network part of the address. These classes are class A, class B, and class C.

What does IP class mean?

IPv4 address classAn IPv4 address class is a categorical division of internet protocol addresses in IPv4-based routing. Separate IP classes are used for different types of networks. … As well, some classes are reserved by the Internet Engineering Task Force (IETF) and the Internet Assigned Numbers Authority (IANA) for specific purposes.

Who uses Class A IP addresses?

Class A IP addresses are used for huge networks, like those deployed by Internet Service Providers (ISPs). Class A IP addresses support up to 16 million hosts (hosts are devices that connect to a network (computers, servers, switches, routers, printers…etc.)

What is a Class C IP address?

Class C network addresses range from 192.0. 0.0 to 223.255. 255.0. There are over 2 million possible Class C networks. Example for a Class C IP address: 192.168.178.1.

What is a 255.255 255.0 subnet?

A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address.

What is IP loopback address?

The Internet Protocol (IP) specifies a loopback network with the (IPv4) address 127.0. 0.0/8. Most IP implementations support a loopback interface (lo0) to represent the loopback facility. Any traffic that a computer program sends on the loopback network is addressed to the same computer.
