For most of the people, a Subnet Calculator isn’t one of the tools that they use daily, so it might seem to be hard to understand in the beginning. Once you’ll get used with a Subnet Calculator you’ll understand what this is and how useful it can be.
What is a Subnet Calculator?
A Subnet Calculator, also known as the IP Subnet Mask Calculator is a tool that enables subnet network calculations using IP addresses, subnet bits, network classes, mask bits, subnet mask.
As a result of this Subnet Calculator you’ll get hexadecimal IP address, wildcard mask, broadcast address, subnet ID, and the subnet address range for the resulting subnet bitmap and the subnet network.
Before starting to use the Subnet Calculator you should know that there are some notes, or rules that you must follow if you want to get the best results from this type of calculator.
There are three different classes: Class A, Class B and Class C. Each of them has a different range for the first octet.
The first octet for Class A addresses ranges between 1 and 126.
The first octet for Class B addresses ranges between 128 and 191.
The first octet for Class C addresses ranges between 192 and 223.
Another important thing that you should take in consideration when you’re using a Subnet Calculator is that you are able to use a single subnet bit. It is also allowed to have a subnet ID with the same final octet as the final octet of the subnet mask (you can have the Class C address 192.168.0.192 with the following subnet mask: 255.255.255.192).
The above rules are accepted, and they are seen as being something “normal”, but there can exist some situations when something might not work because one of these rules.
Subnet Calculator offers you the possibility to create a random IP Address that can be calculated. This tool is useful for people who want to study and learn about subnetting and also to do practical exercises that involve this type of knowledge. It’s good to know that most of the Subnet Calculators are working with IPv6.
If you want to split your network and to get subnets, all you have to do is to enter the address and the netmask of your network. Use your imagination and play with the second netmask until you get a result that fulfills what you actually need.
Try this Subnet Calculator and see how it works, even if it will be a little complicated in the beginning. After you’ll understand the basics, everything will look familiar and you’ll be able to use it for personal purposes.
