## How many subnets is 25?

/28 16 255.255.255.240
/27 32 255.255.255.224
/26 64 255.255.255.192
/25 128 255.255.255.128

## What are the minimum host bits needed if the network has 25 hosts?

Minimum subnet size to accommodate a number of hosts

No. of Host Bits Equivalent prefix length Number of usable IP addresses
5 /27 25-2 = 30
6 /26 26-2 = 62
7 /25 27-2 = 126
8 /24 28-2 = 254

## How many hosts can be on each 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.

## How many hosts can you place on a network with a subnet mask of 24?

## What is the subnet mask for 25?

/ 27 32 255.255.255.224
/ 26 64 255.255.255.192
/ 25 128 255.255.255.128
/ 24 256 255.255.255.0

## How do you calculate hosts per subnet?

To calculate the number of possible hosts per subnet, use the formula 2h – 2, where h equals the number of host bits. The reason two addresses must be subtracted is because of the network address and the broadcast address.

## When segmenting a 27 network with a 30 subnet mask how many networks and hosts are possible?

A subnet mask has 32 bits. If the CIDR notation is /27 it indicates that there are 5 bits left to create subnets. Using the 2n-2 formula, or 25 – 2, or 32 – 2, you see the answer is 30. This is how many hosts you can have on the network.

## What does 23 mean in IP address?

255.255.254.0 /23 512
255.255.252.0 /22 1024
255.255.248.0 /21 2048
255.255.240.0 /20 4096

## What are the minimum host bits needed if the network has 20 hosts?

So back to answer our initial question of the minimum subnet size to accommodate 20 hosts, the minimum number of host bits required is 5 bits (2^5 = 32).

## How many hosts are in a 8 subnet?

Class A

/8 255.0.0.0 16777214
/9 255.128.0.0 8388606
/10 255.192.0.0 4194302
/11 255.224.0.0 2097150

## What does 24 mean in IP address?

2.0/24”, the number “24” refers to how many bits are contained in the network. From this, the number of bits left for address space can be calculated. As all IPv4 networks have 32 bits, and each “section” of the address denoted by the decimal points contains eight bits, “192.0.
