Node.js dns.resolve() vs dns.lookup() : <p>I need to lookup a given host to its corresponding IP in Node.js. There seems to be two native methods of doing this:</p>

<pre><code>&gt; dns.resolve('google.com', (error, addresses) =&gt; { console.error(error); console.log(addresses); });
QueryReqWrap {
  bindingName: 'queryA',
  callback: { [Function: asyncCallback] immediately: true },
  hostname: 'google.com',
  oncomplete: [Function: onresolve],
  domain:
   Domain {
     domain: null,
     _events: { error: [Function] },
     _eventsCount: 1,
     _maxListeners: undefined,
     members: [] } }
&gt; null
[ '216.58.194.174' ]
</code></pre>

<p>And:</p>

<pre><code>&gt; dns.lookup('google.com', (error, address, family) =&gt; { console.error(error); console.log(address); console.log(family); });
GetAddrInfoReqWrap {
  callback: { [Function: asyncCallback] immediately: true },
  family: 0,
  hostname: 'google.com',
  oncomplete: [Function: onlookup],
  domain:
   Domain {
     domain: null,
     _events: { error: [Function] },
     _eventsCount: 1,
     _maxListeners: undefined,
     members: [] } }
&gt; null
216.58.194.174
4
</code></pre>

<p>Both return the same IPv4 address. What is the difference between <code>dns.lookup()</code> and <code>dns.resolve()</code>? Also, which is more performant for lots of requests per second?</p>
