@leichtgewicht/ip-codec

Small package to encode or decode IP addresses from buffers to strings. Supports IPV4 and IPV6.

Usage

The basics are straigthforward

1import { encode, decode, sizeOf, familyOf } from '@leichtgewicht/ip-codec'
2
3const uint8Array = encode("127.0.0.1")
4const str = decode(uint8Array)
5
6try {
7  switch sizeOf(str) {
8    case 4: // IPv4
9    case 16: // IPv6
10  }
11  switch familyOf(str) {
12    case: 1: // IPv4
13    case: 2: // IPv6
14  }
15} catch (err) {
16  // Invalid IP
17}

By default the library will work with Uint8Array's but you can bring your own buffer:

1const buf = Buffer.alloc(4)
2encode('127.0.0.1', buf)

It is also possible to de-encode at a location inside a given buffer

1const buf = Buffer.alloc(10)
2encode('127.0.0.1', buf, 4)

Allocation of a buffer may be difficult if you don't know what type the buffer: you can pass in a generator to allocate it for you:

1encode('127.0.0.1', Buffer.alloc)

You can also de/encode ipv4 or ipv6 specifically:

1import { v4, v6 } from '@leichtgewicht/ip-codec'
2
3v4.decode(v4.encode('127.0.0.1'))
4v6.decode(v6.encode('::'))

History

The code in this package was originally extracted from node-ip and since improved.

Notable changes are the removal of the Buffer dependency and better support for detection of formats and allocation of buffers.
