- Class E, 240-255 – for example, 241.0.0.1. ...
Which class of IP address your system have?
- n indicates a bit used for the network ID.
- H indicates a bit used for the host ID.
- X indicates a bit without a specified purpose.
What are IP address classes?
Class C Public & Private IP Address Range
- Public IP Range: 192.0.0.0 to 223.255.255.0 First octet value range from 192 to 223

How is IP address class determined?
You can identify the class of an IP address by looking at its first octet. Following are the ranges of Class A, B, and C Internet addresses, each with an example address: Class A networks use a default subnet mask of 255.0. 0.0 and have 0-127 as their first octet.
What is a Class A IP address example?
Class A Network In a Class A type of network, the first 8 bits (also called the first octet) identify the network, and the remaining have 24 bits for the host into that network. An example of a Class A address is 102.168. 212.226. Here, “102” helps you identify the network and 168.212.

Private IP address– ... Static IP Address– ... Dynamic IP address–
What do you mean by IP classes?
An 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. Some are used for public internet-accessible IPs and subnets, that is, those networks behind a router (as in classes A, B and C).
Why IP address is divided into classes?
The class of IP address is used to determine the bits used for network ID and host ID and the number of total networks and hosts possible in that particular class. Each ISP or network administrator assigns IP address to each device that is connected to its network.

What is the range of IP addresses?
The range of IP addresses is 128.0.0.0 to 191.255.255.255.
What is IP protocol?
Internet Protocol (IP) is a network layer, host-to-host delivery protocol. It means it delivers a packet from one host to the other with no knowledge about the ports within the host. It is a connection-less protocol that makes it unreliable. Hence, it is often clubbed with TCP.
Is there segregation between host and network address?
There is no segregation of host and network addresses.
Can two hosts have the same IP address?
Two hosts in the same network have the same network ID part but different host ID part. You can also write a Python program to validate the IP address. On the basis of this division, IP addresses are classified into various classes.
How many classes are there in IP?
Based on the following rules, IP addresses are categorized into five classes; A, B, C, D, and E.
How many unique IP addresses can a binary system create?
By using 32 bits with two possible values for each position, the binary system can create 4,294,967,296 (2 32) unique combinations or IP addresses. These addresses can be used without any addressing scheme or with an addressing scheme that arranges them in such a way that it becomes easier to access them.
What is the subnet mask?
IP addresses use an additional component to distinguish between network addresses and host addresses . This component is known as the subnet mask. In simple words, the subnet mask tells, how many bits in the IP address are used as the network address and how many bits are left for the host address .
How many bits are in an IP address?
An IP address consists of 32 bits. These bits are divided into four sections. Sections are separated by a dot (. ). Each section contains 8 bits. 8 bits are equal to 1 byte or 1 octet. The following image shows how bits are organized in an IP address.
What is the addressing scheme for routing?
In this scheme, all addresses are divided into five classes and each address is divided into two addresses: the network address and the host address.
How many IP addresses are there in IPv4?
There are two versions of IP addresses, IPv4 and IPv6. In this tutorial, we will discuss how IPv4 organizes IP addresses. In IPv4, there are 4,294,967,296 IP addresses. These addresses are organized into five IP classes. These classes are A, B, C, D, and F.
What is the second level of hierarchical addressing?
In the second level of the hierarchical addressing scheme, each address is further divided into two addresses: the network address and host address .
What are the different IP addresses?
The IP protocol defines five different address classes: A, B, C, D, and E. The first three classes vary the portion of the address devoted to the network ID and the host ID. Class D is for multicast addresses, which is something else entirely. Class E is experimental, so you can just forget about those too.
How many hosts can a class A IP address accommodate?
This means that each Class A network can accommodate more than 16 million hosts.
Why are IPv4 addresses grouped in classes?
IPv4 addresses are grouped in classes. Why? Well, to determine which of the four octets correspond to the network ID and which correspond to the host ID. The clever designers of IP addresses realized that few networks would need to reserve octets enough to identify tens of thousands of hosts. Rather than waste a bunch of IP addresses, they introduced the idea of IP address classes.
How many bits are in an IPv4 address?
Most of the internet is based on version 4 of the Internet Protocol, also known as IPv4. These addresses are limited to 32-bits. They are usually represented in dotted decimal notation, where each group of eight bits (octet) is represented by one of four decimal numbers. For example, 192.168.136.28.
Why is IPv4 used?
It's more of a choice that people take. IPv4 is largely used because of the ease of working with it . IPv6 offers a great deal of advantages (every person in the world could have his own public IP range, enough for all the devices you can dream of), but they're difficult to work with because of the hexadecimal notation.
How many unique host addresses are there in IPv4?
IPv4 addresses are 32-bit binary numbers, meaning there is something like 4 billion unique host addresses that are possible. Each IP address contains two components, the network address and the host address.
How many hosts can a Class C network have?
A Class C address uses the first three octets for the network ID, and the fourth octet for the host ID. This means a Class C network can accommodate only a modest 254 hosts. That said, they allow for more than 2 million separate networks.
Class-based IP addresses
The first bits of the IP address specify how the rest of the address should be separated into its network and host part. This IP address consists of network ID and Host ID.
Classes of IP address
There are 5 classes of IP address in computer network, which are as follows −
Class D
Class D addresses are reserved for multicasting (a sort of broadcasting, but in a limited area, and only to hosts using the same Class D address). There is nothing Called as network ID and Host ID in Class D.
What is an IP class?
IP Classes. An IP class is a complete range of IP addresses that are designed to provide an addressing scheme that can accommodate small and large scale networks. There are 5 classes that are defined by Internet Assigned Numbers Authority (IANA) as follows: Class A.

How many bits are in an IP address?
In the Format of IP Address, we learned that IP Address consists of four set of binary number with the length of 8 bits. According to the theory of mathematics, the total number of permutation of each set of number is 256 (8th root of 2, i.e. 2x2x2x2x2x2x2x2=256). Therefore each set of number can consist of number in the range of 0 – 255.
