Nameservers vs DNS Records (Beginner)

> If you only learn one DNS concept, learn this: **nameservers decide where DNS is managed.** Records are edited *at the authoritative DNS host*.

1) The simple model

• **Registrar**: where you bought the domain.
• **Nameservers**: which DNS provider is authoritative.
• **DNS records**: the actual entries (A, CNAME, TXT, MX) stored at that provider.

2) What nameservers do

Nameservers answer: “For this domain, who has the official DNS records?”

If your domain uses Cloudflare nameservers, you must edit DNS inside Cloudflare (not at the registrar).

3) What DNS records do

Records answer: “What IP should `@` point to?” or “Where should email be delivered?”

4) The most common beginner failure

You change a record at your registrar, but the nameservers point to another provider. Result: nothing changes.

5) How to quickly tell where to edit

Checklist:

1. Find the domain’s nameservers (at your registrar).

2. Identify the DNS provider those nameservers belong to.

3. Edit records *in that provider’s DNS dashboard*.

6) When to change nameservers

• When moving DNS hosting (e.g., registrar DNS → Cloudflare).
• When a provider requires their nameservers for features (WAF/CDN/advanced DNS).

7) Safety tip for migrations

• Copy all existing records to the new DNS host first.
• Lower TTL before switching.
• Switch nameservers, then verify web + email.
