Domains, DNS & SSL

Own your identity: register a domain, point DNS, and secure everything with SSL — the foundation customers see first.

Who this is for

•Businesses setting up their online identity.

•Developers wiring apps, sites, and email to a domain.

•Students learning how the internet routes names to servers.

How it helps you

•Learning: Understand A/AAAA, CNAME, MX, and TXT records and what each does.

•Business: A branded domain and valid SSL build instant credibility.

•Deployment: Point services correctly the first time and verify before launch.

How to use it

1. Register or connect your domain in the Domain Center.

2. Add the right DNS records for your site, app, and email.

3. Enable SSL so the site loads over HTTPS.

4. Verify everything with the free DNS and SSL checkers.

FAQ

Use A/AAAA for apex domains and CNAME for subdomains pointing at another hostname.

Why is my change not live yet?

DNS caching (TTL) can delay propagation; lower the TTL before planned changes.
