npm install ip-cidr
Module for working with CIDR (v4, v6). Based on ip-address.
const IPCIDR = require("ip-cidr");
const cidr = new IPCIDR("50.165.190.0/23");
if(!cidr.isValid()) {
// do something
}
// get start ip as string
cidr.start();
// get end ip as big integer
cidr.end({ type: "bigInteger" });
// do something with each element of CIDR range
cidr.loop(ip => console.log(ip), { type: "addressObject" });
// get an array of all ip in CIDR range as big integer;
cidr.toArray({ type: "bigInteger" });
// get an array of start and end ip as string [startIpAsString, endIpAsString]
cidr.toRange();
Load /dist/ip-cidr.js as script and get the library in window.IPCIDR
returns "ip-address" module object in the necessary format
options are the same in all of the library functions.
check the address belongs to cidr
get start ip
get end ip
get string cidr as "50.165.190.0/23"
get an array of start and end ip [startIp, endIp]
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
run fn for every element of CIDR range
you can use the same chunk options as in .toArray
