By ConceptScroll Team · Published on 19 June 2026 · 3 min read

If you are wondering what is IP address class 11, this blog gives a straightforward definition and explanation. It helps Class 11 students grasp the concept easily for their NCERT English studies.

Understanding What an IP Address Is

An IP address (Internet Protocol address) is a unique number assigned to each device connected to a computer network. It helps in identifying and locating devices so that data can be sent and received correctly.

  • An IP address looks like four numbers separated by dots (e.g., 192.168.1.1).
  • Each number ranges from 0 to 255.

In Class 11 NCERT studies, understanding IP addresses is essential as it forms the foundation of computer networking.

What Is IP Address Class 11: The Concept of IP Address Classes

IP addresses are divided into classes to organise networks efficiently. This system is called classful addressing and is important to know for Class 11 students.

The five classes are A, B, C, D, and E, but classes A, B, and C are most commonly used for networks.

Each class has:

  • A specific range of addresses
  • A default subnet mask
  • Different numbers of networks and hosts

This classification helps in allocating IP addresses based on network size.

Ranges and Features of IP Address Classes A, B, and C

Here is a comparison of the main IP address classes useful for Class 11 students:

ClassAddress RangeDefault Subnet MaskNetworksHosts per Network
A1.0.0.0 to 126.255.255.255255.0.0.0128 (2^7)16,777,214 (2^24-2)
B128.0.0.0 to 191.255.255.255255.255.0.016,384 (2^14)65,534 (2^16-2)
C192.0.0.0 to 223.255.255.255255.255.255.02,097,152 (2^21)254 (2^8-2)
  • Class A supports very large networks.
  • Class B supports medium-sized networks.
  • Class C supports small networks.

This helps in choosing the right IP class based on network requirements.

How to Identify the Class of an IP Address

To find out the class of an IP address, look at the first number (called the first octet):

  • If it is between 1 and 126, it is Class A.
  • If it is between 128 and 191, it is Class B.
  • If it is between 192 and 223, it is Class C.

For example, the IP address 130.45.67.89 belongs to Class B because 130 is between 128 and 191.

This method is simple and helps in quickly identifying the IP class.

Worked Example: Determining IP Address Class

Let's determine the class of the IP address 192.168.10.5.

  • Step 1: Look at the first octet: 192
  • Step 2: Check the range:
  • 192 falls between 192 and 223
  • Conclusion: The IP address 192.168.10.5 belongs to Class C.

This example shows how to apply the range rules to classify an IP address.

Importance of Learning IP Address Classes for Class 11 Students

Understanding what is IP address class 11 is vital for students because:

  • It builds foundational knowledge of computer networks.
  • Helps in understanding how the internet and local networks work.
  • Is useful for practical computer applications and future studies in IT.
  • Supports NCERT curriculum requirements for Class 11 English and computer science.

Mastering this topic improves problem-solving skills related to networking concepts.
