Yes. That is what this is.
ipl=require('node-ip-lib');
ipAddr = new ipl.ip('192.168.0.1'); // This has an implied CIDR of 32.
// All of the following are Identical.
ipAddr = new ipl.ip('192.168.6.1',24); // CIDR of 24.
ipAddr = new ipl.ip('192.168.6.1','255.255.255.0'); // CIDR of 24, same as above.
ipAddr = new ipl.ip('192.168.6.1',0x00FFFFFF); // CIDR of 24, same as above.
ipAddr = new ipl.ip('192.168.6.1',16777215); // CIDR of 24, same as above.
// All math functions have the same function signature, except "not"
ipAddr.and(16); // gives: 192.168.0.0
ipAddr.and('255.255.0.0'); // gives: 192.168.0.0
ipAddr.and(65535); // gives: 192.168.0.0
// or and xor also available with the same options.
ipAddr.not(); // returns binary inverse of the address eg: "63.87.249.254"
Clone this repository into your node_modules directory.
or
$ npm install node-ip-lib
- Simple Math style functions on IP addresses.
- Write tests.
- Add more stuff.
If you have something that should go here, write it, and I'll include it. Or, spark the idea for me to write it.
