IP Subnet Calculator for IPv4/v6 1.02
Bitcricket ushers in a modern era re-write of the original IP Subnet Calculator for Windows.
With a refreshed GUI, native Windows or Mac operation, and support for IPv6, the IP Subnet Calculator is perfect for quickly computing your subnet mask and address ranges, learning about IPv6, and supporting migration from IPv4 to IPv6.
Automatic Subnet Calculations. Simply input a starting IP address, and your choice of subnet bits or the maximum number of desired subnets or the host bits or the maximum number of desired hosts, and the calculator figures out the all the rest, including a list of subnets. Quick. Easy. Painless.
Export Your Data. A mere cut-and-paste away into your favorite spreadsheet, word processor, or email.
CIDR Support. The subnet calculator makes it easy to generate Classless Interdomain Routing (CIDR) information also known as "supernetting" which allows multiple IP addresses (especially Class C) to be summarized into a smaller set of routing entries.
Migrate to IPv6.The Bitcricket subnet calculator is the first to support IPv6. Although there are no subnets in IPv6 per se (and thus no subnet masks), there are IPv6 network identifiers and several different types and meanings of IPv6 addresses. Simply type in an IPv6 address and we dissect it for you. Or, create your own IPv6 addresses. Furthermore, the calculator helps you with your migration from IPv4 to IPv6.
