# You asked: What is the last valid host on the subnetwork?

Contents

A host can use the broadcast address to send data to all the other hosts on the subnet. It’s the last address on the subnet. We can calculate it by using the network address and adding the total number of addresses (minus one) in the subnet.

## What is the first and last valid host on the subnetwork?

Subnetting Questions

What is the first valid host on the subnetwork that the node 172.26.185.172/24 belongs to? 172.26.185.1

## What is the valid host range of each subnetwork?

Answer: The valid hosts are the numbers between the subnet number and the mask. For the 64 subnet, the valid host range is 64-126. For the 128 subnet, the valid host range is 129-190.

## How do you know if a host is valid on subnetwork?

To find the valid host range, turn all of the host bits off and then turn them on.

1. 10.0 is the network address because all host bits are off.
2. 10.1 is the first valid host.
3. 10.254 is the last valid host.
4. 10.255 is the broadcast address because all host bits are on.

## What is the first valid host on the subnetwork that the node 172.28 71 106 27 belongs to?

It belongs to the 192.168. 35.224 subnet. /30 means only 2 bits are left for hosts.

## What is valid host?

a valid host address means no broadcast address and no subnet address can be used and means that not all 9 bits of host portion can be all 1 or all 0.

## What is the last host address?

A host can use the broadcast address to send data to all the other hosts on the subnet. It’s the last address on the subnet. We can calculate it by using the network address and adding the total number of addresses (minus one) in the subnet.

## How many hosts are in a 22 subnet?

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

/22 255.255.252.0 1,024
/21 255.255.248.0 2,048
/20 255.255.240.0 4,096
/19 255.255.224.0 8,192

## What is a 24 bit subnet mask?

A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address.
