## How many subnets are in a IP address?

Each subnetwork could potentially support up to 30 host addresses. Since you now have four bits to make subnets with, you only have four bits left for host addresses. So in this case you can have up to 16 subnets, each of which can have up to 16 host addresses (14 of which can be assigned to devices).

## How many subnets are created?

Total number of subnets: Using the subnet mask 255.255. 255.248, number value 248 (11111000) indicates that 5 bits are used to identify the subnet. To find the total number of subnets available simply raise 2 to the power of 5 (2^5) and you will find that the result is 32 subnets.

## How do you calculate the number of subnets per host?

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 subnets and hosts are available?

Since the host portion has now lost two bits, the host portion will have only 22 bits (out of the last three octets). This means the complete Class A network is now divided (or subnetted) into four subnets, and each subnet can have 222 hosts (4194304).

## Is there an IP subnet mask calculator?

IP Subnet Calculator. This calculator returns a variety of information regarding Internet Protocol version 4 (IPv4) and IPv6 subnets including possible network addresses, usable host ranges, subnet mask, and IP class, among others.

## How is a subnet characterized in an IPv4 network?

For IPv4, networks can also be characterized using a subnet mask, which are sometimes expressed in dot-decimal notation, as shown in the “Subnet” field in the calculator. All hosts on a subnetwork have the same network prefix, unlike the host identifier which is a unique local identification.

## How to calculate the size of a subnet?

Prefix size Network mask Usable hosts per subnet /1 128.0.0.0 2,147,483,646 /2 192.0.0.0 1,073,741,822 /3 224.0.0.0 536,870,910 /4 240.0.0.0 268,435,454
