About

Module for working with CIDR (v4, v6). Based on ip-address

Example

import CIDR from "ip-cidr-webpack";

let cidr = new CIDR("50.165.190.0/23"); 

if(!cidr.isValid()) {
    // something 
}

cidr.start(); // get start ip as string
cidr.end({ asBigInteger: true }); // get end ip as big integer

let data = [];

const fn = (ip) => {
    // do something with each element of CIDR range    
    data.push(ip) // ip is "ip-address" module object, because of option asAddressObject is true 
}

cidr.arrayAction(fn, { asAddressObject: true });
cidr.toArray({ asBigInteger: true }); // get an array of all ip in CIDR range as big integer;
cidr.toRange(); // get an array of start and end ip as string [startIpAsString, endIpAsString]

Client side

Load /dist/ip-cidr.js as script and get the library in window.IPCIDR

API

.formatIP(address, options)

returns "ip-address" module object in the necessary format
options are the same in all of the library functions and might include asBigInteger, asAddressObject or asString (by default)

.start(options)

get start ip

.toString()

get string cidr as "50.165.190.0/23"

.toRange(options)

get an array of start and end ip startIp, endIp

.toObject(options)

get an object of start and end ip {start: startIp, end: endIp}

get an array of all ip in CIDR range
you can get an information by chunks using options.from and options.limit
this options might be an integer or a big integer("jsbn" instance)
you can pass the second argument "results" (object) to get all chunk pagination information
