MAP: Scan an IP Address Range

  • Article

Scan an IP Address Range

This method allows you to specify the starting address and ending address of an IP address range. The wizard will then scan all IP addresses in the range and inventory only those computers. The IP address range computer discovery method is limited to scanning only 100,000 IP addresses at one time. If you have more addresses than the limit, run the wizard multiple times, specifying different IP address ranges each time you run the wizard.

This discovery method has the following characteristics:

  • Scope – It identifies all computers running Microsoft operating systems with an IP address that falls with the range of addresses provided.
  • Process – MAP will return a list of computer objects within the specified IP address ranges, which WMI then uses to perform a detailed inventory.
  • Limitations – This method supports up to 100,000 computers per MAP inventory session.
  • Credentials required – None

The following recommendations are provided for the IP address range computer discovery method:

  • Use this method to specifically target a set of computers in a branch office or specific subnets when you only want to perform inventory on those computers.
  • Use this method to find devices and computers that cannot be found using the Computer Browser service or AD DS.
  • Limit the size of the IP address range provided. This will reduce the time required to perform inventory.
