What Is The Difference Between Subnet And Subnet Mask?

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 are the 4 parts of an IP address?

The following sections detail how IP addresses are organized and analyzed, with a view to answering subnetting questions.Address Class. … Default Subnet Mask. … The Network Field. … The Host Field. … Non-default Masks. … The Subnet Field.

What exactly is a subnet?

A subnetwork or subnet is a logical subdivision of an IP network. … 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. The rest field is an identifier for a specific host or network interface.

What is the difference between subnet and network?

You’d need to change the subnet mask to 255.255. 254.0 , or use a router or layer-3 switch to communicate. Network generally means the whole network you’re referring to, while subnet refers to a specific separate portion of it.

Can a subnet mask be anything?

A subnet mask hides, or “masks,” the network part of a system’s IP address and leaves only the host part as the machine identifier. A common subnet mask for a Class C IP address is 255.255. 255.0. … The last section of each computer’s IP address can be anything from 0 to 255.

Why is subnet mask 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 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 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 subnet should I use?

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).

How do you define 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. The “255” address is always assigned to a broadcast address, and the “0” address is always assigned to a network address.

Is subnet the same as subnet mask?

Subnet mask is a mask used to determine what subnet an IP address belongs to. An IP address has two components, the network address and the host address.

How do I know 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.
