IP Subnet Calculator
Simple IP calculator, which you can use by simply enterign the needed data. All calculation will be done automatically. This tool may not work with some browsers, so if you think this is so, try visiting this page using a different browser. Sorry for the inconvenience...javascript subnet calculator
The funny thing about a JavaScript Subnet Calculator is that JavaScript integers are only 16 bit. In order to do easy bit shifting you need 32 bit integers. This code weaves it's way through that issue by storing IP address octets in arrays with 4 integers. View source to see/grab the code.
You can use CIDR Netmask in the Network IP field (eg:10.0.0.1/24). Change the network class, network IP, subnet mask, or number of hosts to trigger calculations. This code does work on most browsers including FireFox, Safari, iPhone, iTouch, Android, Blackberry and even IE.
The CIDR Calculator enables CIDR network calculations using IP address calculator, CIDR mask (subnet mask), mask bits, maximum required IP addresses and maximum required subnets.
YanıtlaSilResults of the CIDR calculation provide the wildcard mask, for use with ACL (Access Control Lists), CIDR network address (CIDR route), network address in CIDR notation and the CIDR address range for the resulting CIDR network.
For classful subnets, please use the IP Subnet Calculator. For classful supernets, please use the IP Supernet Calculator. For simple ACL (Access Control List) wildcard mask calculations, please use the ACL Wildcard Mask Calculator.
