[IP Subnet Calculator

Do you use a subnet calculator to help manage your network? An IP subnet calculator is responsible for returning a range of information regarding subnets, subnet masks, network addresses, usable host ranges, IP class, and much more. An IP address stores key information, like the network the device is linked to and details of the device itself.

The device, or computer, is also known as the host. In short, an IP address is the means by which networking equipment identifies the connected network and the host. This becomes more complicated when large organizations with vast networks are brought into the mix. A network can become too big and, in these cases, its performance is likely to worsen.

Subnetting is the solution to this problem. Subnetting lets you break your network down into more manageable pieces. Subnets help a larger network function more effectively and enable an organization to make the most of network capacity. All devices in a subnet are identifiable by a shared, identical bit-group in the IP address.

This visible, logical division separates the IP address into distinct fields: a routing or network prefix, followed by the host identifier or rest field. The rest field represents the identity of a certain network interface or specific host.

This should give you a better awareness of subnet terminology and inform your understanding of the products listed later in this guide. Subnet scanning, as its name suggests, involves conducting a scan to identify websites and IP addresses within the subnet. The scan can report back on the availability status of IP addresses and may report on other details too, including whether an IP is used, available, or transient.

You may also gain insight, depending on the scanner tool, into DNS name, reserved status, switch details, last alive time, MAC address, and last updated time. Remember an IP address has two main elements: the network and host address.

A subnet mask divides the IP address into the network and host address, while subnetting further separates the host element of the IP address into a subnet. Its purpose is to divide the IP address into its host and network address parts, so the subnetting process can begin. Subnet calculators—sometimes known as subnet range calculators or subnet mask calculators—will retrieve subnetwork info from both the IP address and the subnet mask.

The result should be a list of subnets. Subnet calculators are used for a variety of reasons because subnetting serves different purposes for different people. Primarily, IT administrators and professionals use subnets to make their network more organized, as has briefly been touched on already. By partitioning a large network, you can allocate certain addresses to specific departments or teams. It also makes identifying any issues easier, because you can trace the problem back to a smaller subnet.

This helps you pinpoint the source of the problem faster, while searching through an undivided network for the issue can feel like looking for a needle in a haystack.

But there are a couple of other reasons to use subnets. So, if you have used up all the space in one subnet, you can always create another so more IP addresses can be added.

Alternatively, you can alter a subnet mask to change the subnet size, freeing up any unused IP addresses to be used in a different subnet entirely. Many IT professionals use subnetting to boost security. With these reasons for subnetting in mind, the purpose of subnet calculators is simple. In summary, a subnet calculator is used to make subnetting simpler and faster, while subnetting is used to boost organization, capacity, and security.

As subnetting calculators facilitate subnetting, their uses are intertwined and shared. There are several network subnet calculators available.

Some have specific utilities, while others have greater scope and cover a wider range of functions. In your search for the best network subnet calculator, you may encounter the following types:. This list is by no means exhaustive but should give you an idea of the different ways IP subnet calculator tools are executed and described.

Want to start with the best? This toolset was designed to be a cost-effective, all-in-one solution for several IT needs. It includes more than 60 tools covering the essentials of network management, monitoring, and troubleshooting.

Each tool brings something new and fundamental to the table, and yet they work seamlessly in combination with each other. Subnets can be discovered on a seed router.

You can scan an array of IP addresses at once or scan the subnet itself. This subnet calculator stands out because it offers both a classful and classless approach, allowing you to generate a subnet list alongside size, mask, inverse mask, broadcast address, and host range. With this tool, you can stay on top of which IP addresses are in use and which are not. This will improve your awareness of how every subnet is used, which in turn will help with making reserved IP address assignments that are static and free from conflict.

I especially like the graphical depictions of data and the network topology maps. Tunnels Up offers one of many online subnet calculators. This is a free tool and allows users to input the following:. This tool is IPv4 and IPv6 ready. This is another online tool but is surprisingly functional.

Spiceworks is well-known for its range of IT management and monitoring programs, and their applications are generally trustworthy. Their online subnet calculator is no exception. I love the simplicity of this tool, which seems to walk hand-in-hand with its web-based approach, though I wish it were also available as a downloadable, on-premises program. Though the system itself is self-explanatory, Spiceworks nonetheless provides video tutorials to walk you through the process.

To use this program, simply enter the first and last addresses in your network range. Alternatively, you can use the CIDR notation. Then define how many subnets, or the least number of hosts per subnet, and generate. As a result, the tool will show you the beginning and ending IPs, the number of hosts, the subnet mask, and the CIDR notation. At this stage, you can use sliders to change subnet sizes. Spiceworks Subnet Calculator supports IPv4 addresses.

If you want to use the calculator in a more advanced way, plenty of resources are available within the impressive Spiceworks community to help you out.

This program is good for adding new network equipment, calculating ranges, getting subnetting practice, and converting CIDR notation into an IP address range. In my opinion, this is a love it or hate it tool. On the one hand, it can be extremely powerful and efficient when used correctly. It is not especially user-friendly, but its functionality is high quality.

Site24x7 also offers tools for finding IP addresses, checking port availability, generating traceroute, checking Heartbleed vulnerability, generating random passwords, monitoring SSL certificates, DNS analysis, checking brand reputation, and much more. They also have an IPv4 subnet calculator, which functions similarly to the IPv6 subnet calculator. This is a web-based tool, which is an advantage and a disadvantage.

This tool conducts calculations on the network address block provided. The output is subnet address, host range, and subnet notation. All you need to get started is the network address block and to input the number of subnets. For those of you who value simplicity, you can give this tool a go with zero risk. There are lots of subnet calculators out there. Some are web-based, some are specialist, and many are free.

The range of utilities available make this tool a must-have. Subnet Scanning Subnet scanning, as its name suggests, involves conducting a scan to identify websites and IP addresses within the subnet. Back to top Why Use a Subnetting Calculator? In your search for the best network subnet calculator, you may encounter the following types: IPv6 IP Subnet Calculator: This will let you map your own hierarchical subnets.

HEX Subnet Calculator: Works for calculating the first and last subnet addresses, including multicast addresses with hexadecimal notations. Subnet Mask Calculator: Works for determining the smallest available subnet with a corresponding subnet mask.
