# What is a Class C network subnet?

## What is a Class C network subnet?

Class C networks use a default subnet mask of 255.255. 255.0 and have 192-223 as their first octet. The address 192.168. 123.132 is a class C address. Its first octet is 192, which is between 192 and 223, inclusive.

### What are the address ranges of the subnets?

• Class A: 10.0. 0.0 to 10.255. 255.255.
• Class B: 172.16. 0.0 to 172.31. 255.255.
• Class C: 192.168. 0.0 to 192.168. 255.255.

#### How do you calculate the number of subnets in a network?

To calculate the number of possible subnets, use the formula 2n, where n equals the number of host bits borrowed. For example, if three host bits are borrowed, then n=3. 23 = 8, so eight subnets are possible if three host bits are borrowed.

What are the different classes of networks?

Network Class Byte 1 Range Byte 2 Range
A 0-127 1-254
B 128-191 Preassigned by Internet
C 192-223 Preassigned by Internet

How many subnets are in a class C?

128 subnets
Class C /31 borrows 7 bits for the network address from the host address. That gives us 128 subnets, which is 2 to the power of 7. /31 can accommodate two hosts each. The valid host addresses would be 200.15. 10.0 to 200.15.

## What’s a 24 subnet?

24 indicates that the first 24 bits of the address are masked (255.255.255.0). a /16 would translate into 255.255.0.0. Here is some more information you can refer to: Guide | Introduction to IP Addressing. Guide | CIDR and Subnetting.

### How do you calculate the number of networks in a class?

The total number of networks a class address may have is calculated by subtracting the number of bits in the subnet mask from the number of bits used to determine which class of network it is. For example, a class A network has an 8-bit subnet mask.

#### What are the classes of subnetworks?

What are the classes of networks? There are five classes of subnetworks: Class A, Class B, Class C, Class D, and Class E.   Each class relates to a specific range of IP addresses. Classes A, B, and C are used the most often by different networks.

How many network bits are used in a Class B subnet?

By default, using Classful Networking, fourteen bits are used as Network bits providing (2 14) 16384 Networks and (2 16 -1) 65534 Hosts. class B IP Addresses will be subnetted constant means as class A addresses, by borrowing bits from Host bits. Below is given all potential combination of class B subnetting:

What makes a Subnet class unique?

Subnet classes are made unique by the number of bits their IP addresses have dedicated to a network and the number of bits dedicated to hosts. They each have a default subnet mask.

## How many subnets are there in IPv4 Class B?

IPv4 Class B Subnets. By default, using Classful Networking, fourteen bits are used as Network bits providing (2 14) 16384 Networks and (2 16-1) 65534 Hosts. class B IP Addresses will be subnetted constant means as class A addresses, by borrowing bits from Host bits.
