How do I scan larger IP networks?

When selecting a network scan target larger than a /20 network to perform a scan against, the system will automatically identify this and split up the scan in several parts for optimal performance, where scans will be run in parallel. 

With the system splitting up the scan in several scans, you can easily analyze a larger result data set as each scan will produce its own result report. This makes it easy to share reports as the size of each report will be more manageable. 

Each sub-scan will be limited to /20 network, for example:

  • You choose a network scan target that includes a /16 network.
  • The system identifies this as a larger IP network and performs automatic analysis to split it up in several scans.
  • From the initial /16 network, there will be a total of 16 scan jobs running against /20 networks, based on the initial target /16 network.
  • The 16 scan jobs will be executed in parallel for optimal performance and return results when finished per each /20 network.

Note: If you are performing an internal scan on a larger network - it's highly recommended that you use a minimum of 4 scanner appliances to be able to split the load among all of these and get the best performance on your scan. 

Note: Platform API is currently not supporting this functionality.
