DNS records are an essential component of the internet infrastructure. They are responsible for resolving domain names into IP addresses that computers can use to communicate with each other. Without DNS records, navigating the web would be a lot harder. In this blog post, we’ll look at six critical DNS records you need to know. So, let’s start!
