What is Domain Name?

A domain name is the human-readable address used to reach a website, such as roelu.com or stripe.com. It maps to an IP address — a numeric label the internet uses to locate the server hosting your site. Domain names are registered through accredited registrars, renewed annually, and managed via DNS records that point traffic to the right destination. Without a domain name, every site would only be reachable by its IP address.

Why it matters

Your domain is the one piece of digital real estate you actually own. Lose it, and you lose your brand, your email, your SEO history, and your customers' bookmarks in a single afternoon. Most companies treat domain management like office plumbing — forgotten until it leaks. Then renewal lapses, a squatter grabs it, and recovery becomes a five-figure legal problem. Register through a registrar you trust, lock the domain, enable two-factor authentication, and keep ownership in the company's name, not an ex-employee's personal account.

How it works

You buy a domain from a registrar like Cloudflare, Namecheap, or Google Domains for roughly ten to twenty dollars per year. The registrar reserves the name in the global registry for your chosen extension — .com, .io, .ai, and so on. Once registered, you configure DNS records to point the domain at your web host, your email provider, and any other services. When a visitor types the domain into a browser, their device asks DNS where to go, gets the IP address back, and connects to the server. The whole handshake takes milliseconds, and the visitor never sees any of it.
