# Question: How Many Subnets Are There?

## How many 24 subnets are in a 16?

Since you have 8 more bits to use to define the network in the /24 subnets under the /16, there are 256 /24 subnets in a specific /16..

## How many subnets are in a 25?

## How many subnets are in a class C?

Subnetting Class C Addresses 1.0. You need to create 5 sub networks each network has a maximum of 10 hosts. We can only use the first 8 bits for out subnets as these 8 bits have been allocated as host addresses. So Subnet masks of 255.255.

## What is a 16 subnet?

The last three octets of a Class A subnet mask are used to address hosts on a LAN; the 24 bits you can manipulate however you wish. … It saves you from typing, or pronouncing, the whole mask. For example, /8 means 255.0. 0.0, /16 is 255.255. 0.0, and /24 is 255.255.

## How many 20 subnets are in a 16?

## How many subnets are in a 16?

Deduction 240 from 256 gives us 16. So the subnet addresses are 0, 16, 32, 48, 64 … 208, 224, 240.

## What does 24 mean in IP address?

This means that this IP address is in the subnet = 192.168. 1.0 with subnet mask = 255.255. 255.0. Shorthand (AKA CIDR, Classless Inter-Domain Routing), this can be written 192.168. 1.0 /24 where the ‘/24’ represents the number of subnetwork bits active in the mask.

## How many IPs is a 16?

## What destination adress is 255.255 255.255 for?

255.255. 255.255 — This address is reserved for network broadcasts, or messages that should go to all computers on the network. 127.0. 0.1 — This is called the loopback address, meaning your computer’s way of identifying itself, whether or not it has an assigned IP address.

## What is IP subnet?

A subnetwork or subnet is a logical subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting. Computers that belong to a subnet are addressed with an identical most-significant bit-group in their IP addresses.

## What are the valid subnets?

The valid subnets are 64 and 128. … 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 subnets work?

Subnetting works by applying the concept of extended network addresses to individual computer (and another network device) addresses. An extended network address includes both a network address and additional bits that represent the subnet number.

## How many subnets can be created?

x is the number of 1s in the subnet mask. With 1 subnet bit, we can have 21 or 2 subnets. With 2 bits, 22 or 4 subnets, with 3 bits, 23 or 8 subnets, etc.

## How many subnets are in a 24?

Converting /29 gives 255.255. 255.248. This shows that the fourth octet is the interesting octet. Deducting 248 from 256 gives us 8 so the subnets are 0, 8, 16, 24, 32, 40, 48……2-3 Subnetting.Dotted Decimal ValueCIDR notation255.255.255.0/24255.255.255.128/25255.255.255.192/26255.255.255.224/2719 more rows•Dec 12, 2013
