Question: What Is Subnet Mask In Simple Words?

Why do we need IP addresses?

Internet Protocol (IP) addresses are the unique numbers assigned to every computer or device that is connected to the Internet.

Among other important functions, they identify every device connected to the Internet, whether it is a web server, smartphone, mail server, or laptop..

How do you create a subnet?

ProcedureClick the Network tab.In the Subnets tab, click Create.In the Create Subnet dialog box, specify subnet details, such as the name, subnet IP address or subnet mask, range of IP addresses, gateway address, and broadcast domain. … Click Create.

Why default gateway and subnet mask are required?

The subnet mask is used to allow computers to determine whether the addresses of other computers they wish to communicate with are on the local network or on a remote network. If the computer resides on a remote network, the communication request is sent to the default gateway.

What is the difference between subnet and subnet mask?

A subnet denotes a range of addresses that can be allocated to hosts, such as 192.168. 1.0/24. The subnet mask is the classical way of representing which bits are part of the network portion of the address vs. the host bits of the address.

What is IP address and subnet mask?

An IP address is an address used in order to uniquely identify a device on an IP network. The address is made up of 32 binary bits, which can be divisible into a network portion and host portion with the help of a subnet mask. The 32 binary bits are broken into four octets (1 octet = 8 bits).

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.

Why do we need subnet mask?

9 Answers. We need a subnet mask for IPv4 addresses because the address doesn’t give any information on the network size. Class sizes are not the network sizes. … Also to be clear the purpose of the subnet mask is to determine which hosts are on the local network and which are outside of the network.

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

What is the meaning of subnet mask?

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 purpose of subnetting?

Subnetting ensures that traffic destined for a device within a subnet stays in that subnet, which reduces congestion. Through strategic placement of subnets, you can help reduce your network’s load and more efficiently route traffic.

What happens if subnet mask is wrong?

If the netmask is wrong, the program tries to directly access sites where it has to go through the router, or vice versa. The netmask defines, which part of the IP-address is used as address for the network and which part is used for the workstations. Both IPs are in the same net.

What is subnetting and why is it important?

Subnetting identifies a network with a range of Internet Protocol addresses in the Internet. It also allows large networks to be divided into smaller networks, each with its own set of IP addresses.

What is subnetting and its advantages?

Subnetting is the practice of dividing up a network into two or more networks. Common advantages of subnetting include enhancing routing efficiency, network management control, and improving network security.

What does 24 mean in IP address?

The number after the slash represents the number of consecutive 1’s in the subnet mask. For example, 192.168.10.0/24 is equal to the network 192.168.10.0 with a 255.255.255.0 subnet mask. If you convert 255.255.255.0 to binary, you end up with 24 consecutive 1 ‘s: 11111111.11111111.11111111.00000000.

What should subnet mask be?

Most home networks use the default subnet mask of 255.255. 255.0. However, an office network may be configured with a different subnet mask such as 255.255. … This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256).

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. … One goal of a subnet is to split a large network into a grouping of smaller, interconnected networks to help minimize traffic.

How do you find the 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 is Subnet example?

For example, 255.255.255.0 is the subnet mask for the prefix 198.51.100.0/24. Traffic is exchanged between subnetworks through routers when the routing prefixes of the source address and the destination address differ. A router serves as a logical or physical boundary between the subnets.

What is the main purpose of Vlsm?

VLSM is a subnet design strategy that allows all subnet masks to have variable sizes. In VLSM subnetting, network administrators can divide an IP address space into subnets of different sizes, and allocate it according to the individual need on a network.

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.

Is subnet mask always 255?

Again a basic example of a subnet mask uses only the numbers 255 and 0 numbering octets; therefore, to identify the network, any part of the address matched up with a 255 is not changed at all, so the first three octets of the IP address (69, 163, 177) will all be matched with 255 allowing the original numbers to be …
