# Best answer: What is the maximum number of subnets and hosts per subnet?

Contents

The maximum number of available hosts is 4094. You cannot, of course, use the first or last IP in a subnet (e.g. 10.0. 0.0 and 10.0. 15.255) for hosts as these are required for other purposes.

## How many subnets and hosts per subnet would be available?

The classic answer would be to create 256 (2^^8) subnets with 254 (2^^8 – 2) hosts each by using the subnet mask 255.255. 255.0 but in reality you could slice this up any way you want and it is actually legal (although highly unusual) to use non-consecutive bits for your mask, e.g. 255.255.

## What would be the maximum number of hosts per subnet in a class?

Class A

Network Bits Subnet Mask Number of Hosts
/24 255.255.255.0 254
/25 255.255.255.128 126
/26 255.255.255.192 62
/27 255.255.255.224 30

## How do you find the maximum subnet?

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.

## How many hosts are in a 24 subnet?

Subnet Cheat Sheet – 24 Subnet Mask, 30, 26, 27, 29, and other IP Address CIDR Network References

CIDR Subnet mask # of IP addresses
/25 255.255.255.128 128
/24 255.255.255.0 256
/23 255.255.254.0 512
/22 255.255.252.0 1,024

## How do you find the maximum number of hosts?

In simple words, the Number of hosts in any network can be calculated with the formula = 2x– 2, where x is the number of host ID bits in the IP address.

## What is the maximum number of hosts in a 19 subnet?

C. A CIDR address of /19 is 255.255. 224.0. This is a Class B address, so that is only 3 subnet bits, but it provides 13 host bits, or 8 subnets, each with 8,190 hosts.

## What is host per subnet?

Hosts per subnet: 3 bits are left to identify the host therefore the total number of hosts per subnet is 2 to the power of 3 minus 2 (1 address for subnet address and another one for the broadcast address)(2^3-2) which equals to 6 hosts per subnet.

## What is the maximum host for Class C network?

Class C network numbers are appropriate for networks with few hosts–the maximum being 254.

## What is host bit?

Host bits are the portion of an IP address that identify a specific host in a subnet. The subnet mask determines how much of the address is used for network bits and host bits. For example, an IP (v4) address of 192.168. 0.64/26 has a 6-bit host portion, because 26 out of 32 bits are reserved for the network portion.
