Module Usage

To normalize IPv6 addresses

import ip6 from 'ip6';

console.log(ip6.normalize('2404:6800:4003:808::200e'));
// 2404:6800:4003:0808:0000:0000:0000:200e
console.log(ip6.normalize('2404:6800:4003:0808:0000:0000:0000:200e'));
// 2404:6800:4003:0808:0000:0000:0000:200e
console.log(ip6.normalize('2404:6800:4003:808::'));
// 2404:6800:4003:0808:0000:0000:0000:0000
console.log(ip6.normalize('2404:68::'));
// 2404:0068:0000:0000:0000:0000:0000:0000
console.log(ip6.normalize('2404:0068:0000:0000:0000:0000:0000:0000'));
// 2404:0068:0000:0000:0000:0000:0000:0000

// 2404:6800:4003:0808:0000:0000:0000:200e console.log(ip6.normalize('::1')); // 0000:0000:0000:0000:0000:0000:0000:0001

### To `abbreviate` IPv6 addresses

console.log(ip6.abbreviate('2001:0000:0111:0000:0011:0000:0001:0000')); // 2001:0:111:0:11:0:1:0 console.log(ip6.abbreviate('2001:0001:0000:0001:0000:0000:0000:0001')); // 2001:1:0:1::1 console.log(ip6.abbreviate('2001:0001:0000:0001:0000:0000:0000:0000')); // 2001:1:0:1:: console.log(ip6.abbreviate('0000:0000:0000:0000:0000:0000:0000:0000')); // :: console.log(ip6.abbreviate('0000:0000:0000:0000:0000:0000:0000:0001')); // ::1 console.log(ip6.abbreviate('2041:0000:140F:0000:0000:0000:875B:131B')); // 2041:0:140F::875B:131B console.log(ip6.abbreviate('2001:0001:0002:0003:0004:0005:0006:0007')); // 2001:1:2:3:4:5:6:7

### To divide a `/64` subnet into 4 `/66` subnets

let subnets = ip6.divideSubnet("2607:5300:60:1234::", 64, 66); console.log(subnets); / outputs: [ '2607:5300:0060:1234:0000:0000:0000:0000', '2607:5300:0060:1234:4000:0000:0000:0000', '2607:5300:0060:1234:8000:0000:0000:0000', '2607:5300:0060:1234:c000:0000:0000:0000' ] /

### To divide a `/64` subnet into `/128` subnets, but limit to 8 addresses

let subnets = ip6.divideSubnet("2607:5300:60:1234::", 64, 128, 8); console.log(subnets); / [ '2607:5300:0060:1234:0000:0000:0000:0000', '2607:5300:0060:1234:0000:0000:0000:0001', '2607:5300:0060:1234:0000:0000:0000:0002', '2607:5300:0060:1234:0000:0000:0000:0003', '2607:5300:0060:1234:0000:0000:0000:0004', '2607:5300:0060:1234:0000:0000:0000:0005', '2607:5300:0060:1234:0000:0000:0000:0006', '2607:5300:0060:1234:0000:0000:0000:0007' ] /
