Most business owners have heard of DNS — but few know what it actually does. That’s a problem, because when DNS is misconfigured, everything breaks: email stops sending, websites go offline, and trust disappears fast.

Let’s break it down.

DNS = The Internet’s Phone Book

DNS stands for Domain Name System. It’s what translates human-friendly addresses (like yourbusiness.co.uk) into machine-friendly ones (like 198.51.100.2).

Every time someone:

  • Visits your website
  • Sends you an email
  • Loads a tool on your domain

…DNS decides where that request goes.

If DNS is wrong, those requests go nowhere — or worse, to the wrong place.

Why You Should Care

If your DNS isn’t set up properly:

  • Your email might land in spam — or fail altogether
  • You might not own your own settings — especially if a designer or agency registered the domain
  • You could be vulnerable to spoofing, downtime, or misdelivery

For something so critical, most people never log in to check.

The Most Important DNS Records

There are dozens of DNS record types, but here are the ones that matter for most businesses:

  • A Record – Points your domain to a server (for your website)
  • MX Record – Tells the internet where to send your email
  • TXT Record – Used for email authentication (SPF, DKIM, DMARC)
  • CNAME – Useful for pointing subdomains (like mail. or app.) to services you use

Each one serves a different purpose — and all of them need to be accurate.
