One-line answer: Your domain registrar owns your domain name (like a deed to a property address). Your web host stores and serves your website files (like the building on that property). You need both. They can be different companies, and often should be.
What Is a Domain Registrar?
A domain registrar is an ICANN-accredited company that lets you register a domain name — the human-readable address (like "mysevenstars.com") — and maintain ownership of it for as long as you pay the annual renewal fee.
When you register a domain, the registrar records your ownership in ICANN's global registry and assigns your domain to a set of nameservers (usually their own by default). That's it. The registrar doesn't host your website or send your email — it just owns the record that says "mysevenstars.com belongs to Raj Verma."
Registrars also manage domain lock (preventing unauthorized transfers), WHOIS privacy (hiding your personal info from public lookups), and the NS records that tell the internet which DNS provider to query for your domain's records.
What a registrar is responsible for:
- Domain ownership record (in ICANN's registry)
- Annual renewal reminders and billing
- Domain lock / transfer protection
- WHOIS privacy / RDAP data
- NS record management (pointing to your DNS provider)
- Domain transfer to another registrar
What Is Web Hosting?
Web hosting is a service that stores your website's files — HTML, CSS, JavaScript, images, databases — on a server connected to the internet, so anyone who visits your domain can access them.
When someone types your domain name, DNS resolves it to an IP address. That IP address is a web server managed by your hosting provider. The server receives the HTTP request, finds the relevant files, and sends them back to the visitor's browser.
Hosting comes in multiple forms: shared hosting (your site shares a server with hundreds of others), VPS (your own virtual machine on shared hardware), dedicated servers, cloud hosting (AWS, DigitalOcean, GCP), and platform hosting like Vercel or Netlify for static and JAMstack sites.
What a web host is responsible for:
- Storing your website files and databases
- Serving those files to visitors' browsers (HTTP/HTTPS)
- Server uptime and reliability
- SSL certificate (often included)
- Bandwidth and storage capacity
- Backups, security patches, server software
Side-by-Side Comparison
Manages Your Domain Name
- Owns the domain record in ICANN
- Annual fee: $10–$20/yr (most TLDs)
- Controls NS records (→ your DNS provider)
- Provides domain lock & WHOIS privacy
- Handles domain transfers
Serves Your Website Files
- Stores HTML, databases, images
- Monthly fee: $3–$500+/mo
- Gives you an IP address (or CNAME)
- Manages uptime, bandwidth, SSL
- Handles deployments and server config
DNS: The Bridge Between Them
DNS is what connects your domain name to your web host. Here's the chain:
- You register "yourdomain.com" at your registrar (Namecheap)
- You set your NS records at Namecheap to point to your DNS provider (Cloudflare)
- In Cloudflare, you add an A record:
@ → 157.230.75.22(your host's IP) - When someone visits yourdomain.com, DNS resolves it to that IP → your web host answers the request
The registrar and the web host don't talk to each other directly — DNS is the translator between them.
Should You Keep Them Together or Split Them?
Many registrars also offer web hosting, and many web hosts also sell domain registration. Whether to use them from the same company or split them depends on your situation:
| Scenario | Recommendation | Why |
|---|---|---|
| Just getting started, first website | Keep together (temporarily) | Fewer logins, less to configure. Fine for an MVP. Migrate later. |
| Any site you care about long-term | Split them | If your host goes out of business, you still own your domain. Avoids lock-in. |
| Moving web hosts | Separate registrar makes it easier | Just update your A record in DNS. No domain transfer needed, no downtime. |
| GoDaddy bundle deal | Transfer domain away | GoDaddy's hosting is mediocre, their DNS is slow, and their upsell flow is aggressive. Separate them. |
| WordPress on Bluehost | Transfer domain to Namecheap + use Cloudflare DNS | Gives you DNS portability, faster resolution, and DDoS protection for free. |
The ideal setup for most founders: Domain at Namecheap or Cloudflare Registrar (clean, affordable, no upsells) → NS records pointing to Cloudflare DNS (free, fast, secure) → A record pointing to your web host (Vercel, DigitalOcean, SiteGround, whatever you chose). Three services, each doing one thing well.
Can One Company Do Both?
Yes. Several companies are both registrars and hosts:
- GoDaddy: Registrar + shared/VPS hosting. Fine for registration, weak on hosting. Transfer your domains out if using them as a host.
- Namecheap: Registrar + shared hosting. Better registrar than host. Good for keeping your domain; their hosting is average.
- Cloudflare: Registrar (at cost, no markup) + DNS (free, best in class) + CDN/proxy. Does not do web hosting — you still need a web host. This is actually the ideal setup: Cloudflare for registrar + DNS, separate web host for your files.
- Squarespace / Wix / Weebly: These are all-in-one website builders that bundle domain + hosting + CMS. Fine for non-technical users who want everything in one place, but you're locked into their ecosystem and their hosting is priced at a premium.
What Happens If Your Registrar Goes Down?
If your registrar has an outage, your domain registration record is still safe — ICANN maintains a registry that isn't solely controlled by your registrar. However, if your registrar also runs your DNS and their nameservers go down, your domain won't resolve and your site will appear offline.
This is another strong argument for splitting DNS to a dedicated provider like Cloudflare: your DNS runs on Cloudflare's globally distributed network, independent of your registrar's uptime.
Common Beginner Mistakes
- "I bought a domain — where's my website?" — Domain registration doesn't include hosting. You need to set up a web host separately and connect them via DNS.
- "I changed my hosting — why is my site still showing the old one?" — You likely updated your host but forgot to update the A record in your DNS. Or your TTL was high and you're waiting for propagation.
- "I can't access my domain — the host is up." — The problem may be DNS or registrar-level, not the host. Check nameservers and NS records first.
- "I let my domain expire." — Your registrar sends renewal reminders. Pay attention to them. A lapsed domain can be snatched by squatters within days. Set autorenewal on.
Summary
- Domain registrar: Owns your domain name. Costs $10–$20/yr. Controls NS records.
- Web hosting: Stores and serves your website files. Costs $3–$500+/mo depending on scale.
- DNS: The bridge that connects your domain name to your web host's server IP.
- Best setup: Separate registrar, separate DNS (Cloudflare), separate host. Each does its job well; none locks you in.
