Bitcricket IP Subnet Calculator
The Bitcricket IP Subnet Calculator from Wildpackets runs natively on both Windows and Mac OS X. It calculates subnets automatically, the company says, presenting bit-by-bit address visualisation and generating a table of subnets. The software also calculates CIDR routes, supports IPv6, discovers locally configured IPv4 and IPv6 addresses on both Windows and Mac, and enables cut-and-paste extraction on to a spreadsheet, word processor or e-mail.
