A Network With 6 Bits Remaining For The Host Portion Will Have How Many Usable Host Addresses?

A Network With 6 Bits Remaining For The Host Portion Will Have How Many Usable Host Addresses?

A network with 6 bits remaining for the host portion will have 62 usable host addresses. Now let us know how to calculate the total number of the usable host idS on a network if a subnet mask is given to it.

Let us take an example to understand this concept in detail. Let say how many total numbers of the usable host ids we can have on the /24 network?

Here /24 will be considered as the subnet mask.

In the binary language /24 will represent the subnet mask that has all the 24 ones that can be followed by another eight number of the zeros. This is considered the 32-bit length.

These 8 bits of the zeroes can be reserved as the host ids. This host I’d be signed to the host or it can be signed to the computer. This can also be connected to the networking device which is present on a certain network.

Here in order to get the total number of usable ids, we have a simple formula that is called the h=2×-2.

Now let us know what this formula represents. Here the H will represent the total number of the host ids which can be usable. And the term X will stand for the number of the zeroes that of a subnet mask. 

Here the term X will represent that there is the number of the zeroes that are present. For suppose if we have the X number of the zeroes then X is equal to 8.

Now the calculation is as 2^8-2 which is equal to 254.

Hence the total number of host ids that can be used will be 254.

Here we may have a doubt why should be subtracted with the -2.

Now let us know about that in detail. the term 2^X will represent the total number of the host ids that are present. But there are two exceptions for this. 

That is there are two ids, one is the network I’d and the other one is the unique I’d for any certain network.

The network I’d is like the every I’d that has a zip code to it.

Here the last id will represent the network broadcast I’d, this broadcast I’d be represented by any of the hosts on any certain network in order to broadcast.

For this reason, we need to subtract it by 2 from the total number of the host ids. Here is the network I’d and the other one is the broadcast I’d be able to the host that is present on the network.

Hence this will be most helpful for the concept of the subnetting and the subnetting of the subnet.

This IP address will have two portions one is like the host portion and the other one will be as the network portion. Here the network and host portion will be different for the different classes.
