  • Classful Subnet Creator – calculates subnets based on subnet mask, mask bits, host bits, number of subnets and hosts per subnet and generates a range of subnets based on these settings.

This CIDR classless subnetting feature is particularly useful for ISPs, universities, or corporations with many Class C addresses.
  • Subnet Addresses – generates a list of addresses for any subnet, which then becomes the working document from which to assign current and future IP addresses. You can even assign addresses within SolarWinds Free Advanced Subnet Calculator and then print the worksheets.
