ipaddrhash

==========

Implements a predictable addressing scheme for statically assigned IPv6 and

IPv4 addresses based on hostnames. Supports node and modern browsers.

The algorithm used to derive an ip is simple:

    ip = prefix + (sha256(seed) & hostmask)

Installation

------------

```

npm install ipaddrhash --save-dev

```

Usage

-----

ESM:

```javascript

import { ipaddrHash, ipaddrPrefixSize } from "ipaddrhash";

```

CommonJS:

```javascript

const { ipaddrHash, ipaddrPrefixSize } = require("ipaddrhash");

```

Example:

```javascript

const prefix = "2001:db8::/64";

const fqdn = "example.com";

const size = ipaddrPrefixSize(prefix);

if (size !== undefined && fqdn.length > 0) {

  ipaddrHash(size, prefix, fqdn).then((result) => {

    // should output:

    // 2001:db8::13d2:1255:86ce:1947

    console.log(result);

  });

}

```
