Key Features of the DNS Module:

• Resolves domain names to IP addresses.
• Can resolve reverse DNS lookups (IP address to domain).
• Provides support for querying DNS servers and caching DNS results.

The DNS module allows you to programmatically query DNS records, resolve domain names, and perform other DNS-related tasks.

Commonly Used Methods in the DNS Module:

1. dns.lookup(hostname[, family], callback)

• Resolves a domain name (hostname) to an IP address.
• The family argument specifies whether to resolve to IPv4 (4) or IPv6 (6).
• The callback function receives the resolved address.

const dns = require('dns');

dns.lookup('example.com', (err, address, family) => {
  if (err) {
    console.error(err);
  } else {
    console.log('Address:', address)…
