Once you have decided to divide a network into subnets, you’ll need a subnet mask. In this guide, there will be mention of subnet mask calculators, so it’s important to understand what a subnet mask is.

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. 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. Subnet scanning, as its name suggests, involves conducting a scan to identify websites and IP addresses within the subnet. This should give you a better awareness of subnet terminology and inform your understanding of the products listed later in this guide. The rest field represents the identity of a certain network interface or specific host.īefore going into what IP subnet calculators do and why we use them, I’ll quickly break down subnet masks and subnet scanning. This visible, logical division separates the IP address into distinct fields: a routing or network prefix, followed by the host identifier or rest field. With subnets, you can split the network up into “departments,” dividing it up so the correct information stays with the appropriate team.Īll devices in a subnet are identifiable by a shared, identical bit-group in the IP address. Subnets help a larger network function more effectively and enable an organization to make the most of network capacity. These smaller networks within the network are called “subnets.” Having these subnets allows more people to be added to a network without creating congestion. Subnetting lets you break your network down into more manageable pieces. Subnetting is the solution to this problem. This is caused by congestion, or traffic, overwhelming the network’s capacity. A network can become too big and, in these cases, its performance is likely to worsen. This becomes more complicated when large organizations with vast networks are brought into the mix. This is of vital importance because if the hardware can’t identify which network a host is connected to, it can’t deliver information to it. In short, an IP address is the means by which networking equipment identifies the connected network and the host. The device, or computer, is also known as the host. An IP address stores key information, like the network the device is linked to and details of the device itself.
To understand subnets, you’ll first need to understand IP addresses. Skip to 6 Best Subnet Calculators List > What Is a Subnet? For a free, easy-to-use tool, try SolarWinds Advanced Subnet Calculator.

If you’re interested in checking out an excellent subnet calculator, I recommend starting with SolarWinds ® Engineer’s Toolset ™ - you’ll get an enterprise-grade subnet tool, plus other incredibly useful network management features. In this guide, I’ll explain how these automated calculators can help you better understand IP addresses and subnets. What a subnet calculator does differs between tools, which is why it’s so important to carefully consider which subnet calculator and subnet scanning utilities are best suited to you and your organization. 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.
