How to Change Nameservers in 2026 (Step-by-Step, Every Registrar)

Quick answer: Change nameservers at your domain registrar (where you bought the domain, not where you host): find DNS/Nameserver settings → replace with your new host's pair → save → wait 1-48 hours for propagation. Keep old hosting active until the new site is confirmed live.
The 4-Step Process
- 1. Get the new nameservers — from your new host's welcome email or dashboard (Bluehost: ns1.bluehost.com / ns2.bluehost.com).
- 2. Log into your registrar — the company you bought the domain from (not your host — see registrar comparison if unsure which is which).
- 3. Replace nameservers — DNS Settings → Custom Nameservers → paste the new pair → save.
- 4. Wait and verify — propagation runs 1-48h; check with a DNS checker tool. Keep the old host live until confirmed.
Per-Registrar Quick Paths
| Registrar | Path to nameservers |
|---|---|
| Namecheap | Domain List → Manage → Nameservers → Custom DNS |
| GoDaddy | My Products → DNS → Nameservers → Change |
| Cloudflare | Can't change — Cloudflare IS your DNS; point via DNS records instead |
| Google/Squarespace | Domains → DNS → Custom nameservers |
The Mistakes That Cause Downtime
- Cancelling old hosting first — migrate fully, verify, THEN cancel. Our migration guide orders it correctly.
- Forgetting email (MX) records — email breaks when nameservers change. Export MX records first, recreate at the new DNS.
- Changing nameservers before the site is ready — during propagation, some visitors hit the new host; if nothing's there, they see nothing.
Context: DNS records explained for what each record does, and subdomain vs subdirectory if you're structuring a bigger move.

Frequently Asked Questions
How do I change my nameservers?
Log into your domain registrar (GoDaddy, Namecheap, Cloudflare, wherever you bought the domain) → find DNS/Nameserver settings → replace the existing nameservers with your new host's pair (e.g., ns1.host.com, ns2.host.com) → save. Propagation takes 1-48 hours.
How long do nameserver changes take?
Officially up to 48 hours, typically 1-4 hours in practice. During propagation some visitors see the old site, some see the new — that's why you migrate the site fully BEFORE changing nameservers, so both versions work.
Where do I find my new host's nameservers?
In your hosting welcome email or dashboard — Bluehost's are ns1.bluehost.com / ns2.bluehost.com, shown in your account panel. Any host's support can confirm theirs in one chat message.
Will changing nameservers cause downtime?
Not if done right — keep the old hosting active until propagation completes (both servers serve the site during the transition). Downtime happens when you cancel the old host before the new one is confirmed live.
Should I change nameservers or just A records?
Nameservers for simplicity — the new host manages all your DNS. A records (pointing only the domain) for control — keep your registrar's DNS if you need custom records (email at one provider, site at another, subdomains elsewhere).
What happens to my email when I change nameservers?
Email follows DNS — if your MX records live at the old host's nameservers, switching breaks email until you recreate them at the new DNS. Export or note your MX records BEFORE switching, then re-add them at the new host.
