dns-equal

What is dns-equal?

The dns-equal npm package is a simple utility for comparing DNS record names in a case-insensitive manner. It is particularly useful when working with DNS records where the case of the characters should not affect the comparison result.

What are dns-equal's main functionalities?

Case-Insensitive DNS Name Comparison

This feature allows you to compare two DNS names in a case-insensitive manner. The code sample demonstrates how to use the dns-equal package to check if 'example.com' and 'EXAMPLE.COM' are considered equal.

const dnsEqual = require('dns-equal');

const name1 = 'example.com';
const name2 = 'EXAMPLE.COM';

console.log(dnsEqual(name1, name2)); // true
