# Quick Answer: How Many 20 Subnets Are In A 16?

## What is a 16 subnet?

The number 16 is the first subnet and also your block size.

The valid subnets in this example are 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, 192, 208, 224.

As another example, if you had a Class A subnet mask of 255.255.

240.0, you’d use the mask on the second and third octets minus 256..

## What does it mean 192.168 0.0 24?

192.168.0.0 Refers to the IP adress /24 refers to the subnet. / 24 subnet is 255.255.255.0. 192.168.0.0/24 is common for home networks.

## What is the 24 at the end of an IP address?

This is called “slash notation”. There is a total of 32 bits in IPv4 address space. For example, if a network has the address “192.0. 2.0/24”, the number “24” refers to how many bits are contained in the network.

## What does the 16 mean in an IP address?

The `/16′ means that the first 16 binary digits is the network address, in other words, the `1.2. ‘ part is the the network (remember: each digit represents 8 binary digits). This means any IP address beginning with `1.2. … 0.0/8’ is a big network containing any address from 10.0. 0.0 to 10.255.

## How many 24s are in a 16?

256 /24s2020 IPv4 Address Space Requests / Delegations networks that ARIN actually allocates. One /19 equals 32 /24s. One /16 equals 256 /24s.

## How do you calculate the number of subnets?

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.

## What does 192.168 mean?

Using 192.168. 192.168. 0.0 is the beginning of the private IP address range that includes all IP addresses through 192.168. 255.255. This IP address is usually not used on a network, and a phone or computer wouldn’t be assigned this address.

## What does CIDR 16 mean?

/16, /24 is called CIDR notation, it’s a different way to express the subnet mask. … CIDR just says we can simply say the number of 1 bits without writing out the four decimal numbers of the subnet mask. So you can write 192.168. 0.5/24 instead of 192.168. 0.5/255.255.

## What is a 255.255 254.0 subnet?

It means that you decided to use the last 8 bits of the address for your devices. 8 binary bits gives you 256 decimal, so you can have 256 addresses for the devices on your network ranging from 192.168. … You change the network mask to 255.255. 254.0. Now you have 9 bits for your devices (254 is 11111110).
