Convert IPv4 or IPv6 address to the Buffer.

## Usage

```js

const { pton4, pton6 } = require('ip2buf')

pton4('8.8.8.8') // Buffer<0x8, 0x8, 0x8, 0x8>

pton6('2001::')  // Buffer<0x20, 0x01, 0, ...>

```

## API

* `pton(af: number, addr: string, [[dest: Buffer], index: number]): Buffer`

Convert IPv4 or IPv6 address to the Buffer.

```js

const { pton, constants: { IPV4_OCTETS, IPV6_OCTETS } } = require('ip2buf')

pton(IPV4_OCTETS, '127.0.0.1')

pton(IPV6_OCTETS, '::1')

```

* `pton4(addr: string, [[dest: Buffer], index: number]): Buffer`

Convert IPv4 address to the Buffer.

* `pton6(addr: string, [[dest: Buffer], index: number]): Buffer`

Convert IPv6 address to the Buffer.

* `constants: Object`

  - `IPV4_OCTETS` - size of IPv4 target buffer.

  - `IPV6_OCTETS` - size of IPv6 target buffer.
