# How do I create a subnet mask?

## How do I create a subnet mask?

1. Step 1: Determine the network class of the given IP Address 192.35.
2. Step 2: As the IP starts with 192, the address falls on Class C.
3. Step 3: Calculate Number of bits, to define the subnets.
4. Step 4: Formula to calculate Number of bits = Log2(Number of subnets + 2).

How do you subnet step by step?

255.248 or /29.

1. Step 1: Convert to Binary.
2. 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.
3. Step 3: Find Host Range.
4. Step 4: Calculate the Total Number of Subnets and.

### What is subnet mask in easy way?

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.

How do you use a subnet mask?

## What does subnet mask 255.255 255.0 tell a router?

What does the subnet mask 255.255. 255.0 tell a router? The purpose of the part of the mask that reads 255, or all 1s in binary, is to tell a router what part of an IP address is the subnet ID.
