# Question: What Is Difference Between Subnet And Subnet Mask?

## How do you subnet?

255.248 or /29.STEP 1: Convert to Binary.STEP 2: Calculate the Subnet Address.

To calculate the IP Address Subnet you need to perform a bit-wise AND operation (1+1=1, 1+0 or 0+1 =0, 0+0=0) on the host IP address and subnet mask.

STEP 3: Find Host Range.

STEP 4: Calculate the Total Number of Subnets and Hosts Per Subnet..

## What is subnet simple words?

A subnet, or subnetwork, is a segmented piece of a larger network. More specifically, subnets are a logical partition of an IP network into multiple, smaller network segments. … Each computer, or host, on the internet has at least one IP address as a unique identifier.

## What does CIDR 16 mean?

0.0 up to 192.168. 255.255 Small network). It means you have used sixteen bits for network address out of thirty two bits and bits are remaining for host addressing. for these remaining sixteen bits can be used for sub netting based on your network design and other sub netting steps illustrate in above posts.

## What is subnet mask and why it is used?

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 (Internet Protocol) address and see how it is organized.

## What exactly is a 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. … This results in the logical division of an IP address into two fields: the network number or routing prefix and the rest field or host identifier.

## How many subnets are there?

Network BitsSubnet MaskNumber of Subnets/24255.255.255.00/25255.255.255.1282 (0)/26255.255.255.1924 (2)/27255.255.255.2248 (6)3 more rows•Aug 16, 2003

## What is a zero subnet?

Subnet zero is the subnet which has all binary 0’s in the address. So for the number 192.168. 1.0 you have in the last octet eight zeros for the subnet number or 00000000. The last octet has all 1’s in the subnet part.

## What is a 255.255 254.0 subnet?

255.255.254.0 = 23 bits mask = 510 hosts (512 -2 ) 255.255.252.0 = 22 bits mask = 1022 hosts (1024 -2 ) 255.255.248.0 = 21 bits mask = 2046 hosts (2048 -2) You always multiply by 2 or divide by 2..and remove 2 hosts (broadcast and network)

## What is a 16 subnet?

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. 255.0.

## How many IPs is a 16?

– Wildcard Mask can be calculated as network bits = 0 and host bits = 1 so we can say that wildcard mask is just oppsite to subnet mask. while some protocols like eigrp , ospf ,bgp use wildcard mask in their network command to enable these protocols on specific interfaces instead on complete router .

## How do I find my subnet mask?

In the Windows search fields, type cmd, to open command prompt.Press Enter.Type ipconfig/all press Enter.Find your network settings.Your PC’s IP address and your network Subnet Mask and Gateway will be listed.

## What does a subnet look like?

The subnet mask looks a lot like an ip address. It is made up of four eight bit numbers separated by periods. These numbers once again range from 0 to 255. A typical subnet mask is 255.255.

## What is my IP subnet mask?

What Is My Subnet Mask? The most simple way to find your own subnet mask is to run a simple command line in windows. Simply press the Windows key and “R” at the same time to open the command prompt and type “cmd” followed by “enter.” This will allow you to see your subnet mask (as shown below!).

## What is the subnet mask for?

A subnet mask is a 32-bit number created by setting host bits to all 0s and setting network bits to all 1s. In this way, the subnet mask separates the IP address into the network and host addresses.

## What is a Classful subnet mask?

All Class A Classful IP Addresses have an 8 bit subnet mask (255.0. 0.0). On the other hand, the use of an IP Address with a subnet mask other than the default results in the standard Host bits (the Bits used to indentify the HOST ID) being divided in to two parts: a Subnet ID and Host ID.

## How do I subnet in Vlsm?

IPv4 – VLSMStep – 1. Make a list of Subnets possible.Step – 2. Sort the requirements of IPs in descending order (Highest to Lowest). … Step – 3. Allocate the highest range of IPs to the highest requirement, so let’s assign 192.168. … Step – 4. Allocate the next highest range, so let’s assign 192.168. … Step – 5. … Step – 6.

## What is standard subnet mask?

Most home networks use the default subnet mask of 255.255. 255.0. … Large networks with several thousand machines may use a subnet mask of 255.255. 0.0. This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256).

## Who uses Class A IP addresses?

Class A IP addresses are used for huge networks, like those deployed by Internet Service Providers (ISPs). Class A IP addresses support up to 16 million hosts (hosts are devices that connect to a network (computers, servers, switches, routers, printers…etc.)
