Optimize the subnetting process by starting with subnet scanning and IP subnet discovery

IP Subnetting - Manage and Monitor IP Subnets 4 Features Array Item - features item image

Before you manage subnets, you must know how your network is being used. Until you break down your current network organization, you cannot effectively redesign your network according to subnets or keep up with changes.

Subnet scanning helps document your network by identifying existing subnets, displaying how IP addresses are being used, and referencing subnet lists and IP address lists. The subnet calculator in SolarWinds® Engineer’s Toolset (ETS) makes this process quicker and easier.

Master your IP network with a comprehensive, enterprise-grade subnet calculator

If you need to create a new IP subnet or combine existing subnets, you need a subnet calculator to help you with the process. One small mistake can lead to problems in your network. For example, when subnets overlap it can cause routing errors because affected addresses exist in two different subnets.

A subnet range calculator can help you easily and accurately define subnet boundaries and provide you with the needed subnet mask, inverse mask, subnet size, host range, and broadcast address.

Use a subnet calculator to organize your IP address space through IP address tracking

IP Subnet Calculator – Subnet Mask Calculator 2 Features Array Item - features item image

Once you’ve used a subnet calculator’s subnet discovery function to scan your network, the next step in effective IP network management is knowing how each IP address within each subnet is being used. The IP subnet calculator in ETS can help you track which IP addresses are in use or available. This IP tracking helps you understand how each subnet is utilized and assists you in making conflict-free static and reserved IP address assignments.

Easily find out how many subnets you have on your network with a subnet mask calculator

What is SolarWinds Engineer’s Toolset (ETS)?

Subnet masks contain valuable information about how many IP addresses are available within a network. Network administrators can use this information to partition their network into subnets more effectively and find host locations.

Finding out how many subnets you have on your network via the subnet mask can be calculated manually, but a subnet mask calculator can do it in a fraction of the time. Plug the IP address range into the subnet mask calculator and it’ll provide the subnet mask.

Do you find yourself asking…

  • A subnet calculator is a tool network administrators and IT professionals use to quickly and accurately calculate subnets on a network. Once you enter a range of IP addresses into a subnet calculator, it’ll discover subnets on a seed router and scan the subnet or a range of IP addresses to automatically generate a list of subnets along with their mask, size, range, and broadcast address. An enterprise-grade subnet calculator will also be able to actively monitor subnets to identify and track which IP addresses are in use on your network.

    After you have your list of subnets, you can customize them as you see fit. For instance, you can adjust the size of each individual subnet, since not all subnets have to be the same size. If you deal with subnets on a daily basis, a subnet calculator is an indispensable tool to have in your toolset.
