DNS

What Is DNS?

Short definition:
DNS (Domain Name System) translates website names (like google.com) into IP addresses computers can understand.

What this actually means for a business:
DNS is what allows users to access your website, email, and online services reliably—it’s a critical behind-the-scenes system.

Common misconception:
Most people don’t realize DNS exists until something breaks. When DNS fails, websites and email can stop working.

When this matters:
If your website, email, or online services go down unexpectedly, DNS is often part of the issue.
