DNS

DNS (Domain Name System) is the internet’s address book, translating human-friendly domain names like “scottkrukowski.com” into the numeric IP addresses that computers actually use to find each other. When you type a URL into your browser, a DNS lookup happens behind the scenes in milliseconds, routing your request to the right server. DNS also handles other important mappings beyond websites, like directing email to the right mail server and verifying domain ownership for various services.

The Simple Version

Every computer on the internet has a numeric address, like 216.198.79.1. But nobody wants to type numbers to visit a website. DNS (Domain Name System) is the translation layer that turns “scottkrukowski.com” into the number your browser actually needs.

It’s a phone book. You look up a name, you get a number. Your browser does this automatically every time you type a web address.

Why It Matters

DNS is invisible until it breaks. When a website “goes down,” it’s sometimes not the website itself but the DNS that’s misconfigured. The name can’t be translated to an address, so your browser doesn’t know where to go.

If you own a domain name and want to point it at a hosting service, you’ll need to update your DNS settings. It’s the step that connects your human-readable name to the computer that actually serves your site.

How It’s Used on This Site

The domain scottkrukowski.com is registered through IONOS. DNS records point that name to Vercel’s servers, where the site is hosted. When you type the domain, DNS translates it to Vercel’s address, and Vercel delivers the site. Setting up those DNS records was one of the first steps in getting this site live.
