Day 24: Domains and DNS

A domain is a human-readable address for your website. Instead of `random-string.vercel.app`, you could have `yourname.com`. DNS is like the internet's phone book, connecting domains to servers.

Today's Tasks

  1. 1Understand how domains work
  2. 2Either: Add a custom domain you own, OR understand the process for later
  3. 3Explore Vercel's free subdomain option

Prompt to Use

Explain how domains work - how does typing a URL lead to my website? I [do/don't] have a custom domain. [If yes: help me connect it to Vercel. If no: explain what I'd need to do when I get one.]

Expected Outcome

Understanding of domains and DNS.

New Terms

Pro Tip

You don't need a custom domain to launch. `yourproject.vercel.app` works fine for learning and portfolios.

Coming Tomorrow

We'll handle environment variables in production.
