## What is the number of host bits per subnet?

How Many Hosts and How Many Subnets

Number of network bits 8 24
Number of host bits 16 8
Number of subnet bits 8
Number of hosts per subnet 216 – 2, or 65,534 28 – 2, or 254

## How many host bits are in a 24?

Number of bits for Class C networks — 24 bit mask = 255.255. 255.0, 32 bit mask = 255.255. 255.255. USABLE SUBNETS AND ADDRESSES The top and bottom host numbers of any subnet may not be used.

## What are hosts in a subnet?

A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs. To better understand how IP addresses and subnet masks work, look at an IP address and see how it’s organized.

## 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.

## How many hosts are in a 8 subnet?

Class A

Network Bits Subnet Mask Number of Hosts
/8 255.0.0.0 16777214
/9 255.128.0.0 8388606
/10 255.192.0.0 4194302
/11 255.224.0.0 2097150

## How do I know what bit my mask is?

Calculate the subnet bits by looking at the final 8-bit binary word of the 32-bit binary subnet mask. If the final 8-bit binary word is 10000000, then there is one subnet bit and therefore 25 mask bits. If it is 11000000, then there are two subnet bits and therefore 26 mask bits.

## What is host bits and network bit?

An IP address is 32 bits long and made up of two components, a network portion and a host portion. The network address is used to identify the network and is common to all the devices attached to the network. The host (or node) address is used to identify a particular device attached to the network.

## What is the host part of an IP address?

Host Part. This is the part of the IP address that you assign to each host. It uniquely identifies this machine on your network. Note that for each host on your network, the network part of the address will be the same, but the host part must be different.
