Documentation

isme takes a ip string, and returns true if is was recognised as a network interface address. There is a second optional argument there limits the scan, it can be local, public or any.

  var isme = require('isme');
  var assert = require('assert');

  assert.ok(isme('127.0.0.1')); // IPv4 works
  assert.ok(isme('::1')); // IPv6 works
  assert.ok(isme('0.0.0.0')); // any IPv4 works
  assert.ok(isme('::0')); // any IPv6 works
  assert.ok(isme('192.168.0.198')); // public IPv4

  //'local' only matchs loopback addresses
  assert.equal(isme('::1', 'local'), true);
  assert.equal(isme('192.168.0.198', 'local'), false);

  //'public' only matchs public addresses
  assert.equal(isme('::1', 'local'), false);
  assert.equal(isme('192.168.0.198', 'local'), true);

  //'any' only matchs any addresses
  assert.equal(isme('0.0.0.0', 'any'), true);
  assert.equal(isme('::0', 'any'), true);
  assert.equal(isme('127.0.0.1', 'any'), false); // anything else fails
