Perfect for supporting your IPv4 network. Perfect for learning Pv6. Perfect for migration.
One of the most popular IP Subnet Calculators in use today was pioneered by Net3 Group, a company formed by Bitcricket founder J. Scott Haugdahl and subsequently acquired by WildPackets. Bitcricket ushers in a modern era rewrite of this tool, improving upon the precedent set by the original with a refreshed GUI, native Windows or Mac operation, and support for IPv6.
· Calculate Subnets Automatically. Simply input an IP address and choose one of the following: number of subnet bits, the maximum number of desired subnets, the number of host bits, or the maximum number of desired hosts. Our calculator figures out the all the rest, giving you a bit-by-bit address visualization and generating a complete table of subnets. Quick. Easy. Painless.
· Calculate CIDR Routes. Classless Interdomain Routing, also known as "supernetting," allows multiple IP routes (especially Class C) to be aggregated into a smaller set of routing table entries. Just as with subnetting, the subnet calculator makes it easy visualize and generate CIDR information."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
