A dead simple parser for IPv4 and IPv6 ranges, written in Typescript.
ip-range is a dead simple and super flexable parser for IP ranges, written in Typescript. It supports both IPv4 and IPv6 in CIDR notation (192.168.1.0/24) and hyphenated ranges (192.168.1.12-192.168.1.24)
$ npm i @network-utils/ip-range
import { parseRange, ipsBetween } from '@network-utils/ip-range'
// These could be IPv6 also.
const ipsFromCIDR = parseRange('192.168.1.120/29')
const ipsFromHyphenatedRange = parseRange('192.168.1.121-192.168.1.126')
const ipsFromRange = ipsBetween('192.168.1.121', '192.168.1.126')
/*
All three output:
[
'192.168.1.121',
'192.168.1.122',
'192.168.1.123',
'192.168.1.124',
'192.168.1.125',
'192.168.1.126'
]
*/
// parseRange also accepts multi-dimensional arrays
// so you can mix-and-match however you want
const totallyWorks = parseRange(['192.168.1.120/29', ['10.0.0.2-10.0.0.8', '192.168.0.8-192.168.0.12']])

type iprangeA string or array of strings, recursive
type iprange = string | iprange[]
parseRange(range: iprange): string[]Parses an ip range or an array of ip ranges into an array containing each ip within the range(s)
Throws an "InvalidRange" error if range is invalid
ipsBetween(firstIP: string, lastIP: string): string[]Returns an array of every IP address between firstIP and lastIP (inclusive)
Throws an "InvalidRange" error if firstIP or lastIP are not a valid IP address
