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.
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)); // trueThe dns-packet package is a more comprehensive library for encoding and decoding DNS packets. While it offers more functionality than dns-equal, such as parsing and building DNS messages, it does not focus solely on case-insensitive comparison of DNS names.
The dns-txt package is designed for encoding and decoding DNS TXT records. It provides utilities for working with DNS TXT records but does not offer the simple case-insensitive comparison feature that dns-equal provides.
The node-dns package is a DNS server and client library for Node.js. It provides a wide range of DNS functionalities, including querying and serving DNS records. However, it does not specifically focus on case-insensitive DNS name comparison like dns-equal.
Compare DNS record strings for equality. Enforces RFC 1035 domain comparison.
npm install dns-equal --save
var dnsEqual = require('dns-equal')
var domain1 = 'Example.COM'
var domain2 = 'example.com'
if (dnsEqual(domain1, domain2)) {
console.log('The two domains are the same')
}
