Learn why changing nameservers changes which DNS provider answers for your domain.
Short answer
A nameserver tells the internet where to ask for DNS answers. If you move a domain to Cloudflare DNS, the registrar must point to Cloudflare nameservers.
Migration checklist
Copy all important records before switching
Update nameservers at the registrar
Wait for public DNS to reflect the change
Test website and email records
Common mistake
Users often edit records in the old DNS panel after nameservers have changed. Those edits no longer control live DNS.
FAQ
Is changing nameservers the same as transferring a domain?
No. Nameservers control DNS. A registrar transfer changes where the domain is managed.
Can nameserver changes break email?
Yes, if MX and TXT records are not copied to the new DNS provider.
