DNS

In plain English

Every website actually lives on a server with a string of numbers for an address (an IP address). Nobody wants to type numbers, so DNS is the address book that translates your friendly domain name — yourbusiness.com — into that numeric address behind the scenes. When someone visits your site, their browser quietly asks DNS "where does this name live?" and gets pointed to the right place.

Why it matters for your business

DNS is invisible until it isn't. If it's set up wrong — or a change is made carelessly — your website or your email can stop working entirely, even though nothing's actually wrong with the site itself. It's also what you update when you move hosts, add email, or set up security. Small DNS mistakes cause big, confusing outages, which is exactly why it's worth letting someone who does it every day handle the changes.

When you'll run into it

Moving to new hosting, setting up business email, adding an SSL certificate, or pointing a new domain at your site all involve DNS. Done right, the switch is seamless. Done wrong, your site goes dark.
