There is a lot more to managing your IP network than simple subnetting

Network discovery

Before you can manage subnets, you need to know how your network is being used. Do you know?

Network subnetting

Whether you are creating or combining subnets, one mistake can cause problems. Do you have the tools to make error-free changes?

IP address tracking

Once the network is organized, do you have the tools to track which IP addresses are in use or available?

Manage your IP network from discovery to address tracking

  1. IP subnet discovery and scanning

    Most networks are highly dynamic, and many have changed over time. Whether you are trying to re-architect your network or keep up with changes, the first step is knowing how your network is currently organized. Running a network discovery will help you document your network by identifying existing subnets and showing you how IP addresses are being used by using subnet lists and IP address lists. The IP tools in SolarWinds Engineer's Toolset can help.

  2. Classful and classless subnet calculator

    Whether you need to create a new IP subnet or combine existing subnets, you need reliable tools to help you with the process. One common problem occurs when subnets overlap. This often causes routing errors because affected addresses exist in two different subnets. The IP tools in SolarWinds Engineer's Toolset 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.

  3. IP address tracking

    Knowing how your IP address space is organized is the first step to understanding how your network is being used. The next step is knowing how each IP address within each subnet is being used. The IP tools in Engineer's Toolset can regularly scan your subnets and identify how addresses are being used. This tracking helps you understand how each subnet is utilized, and assists you in making conflict-free static and reserved IP address assignments.
