Updated
Nameservers identify the service managing your DNS zone. Records inside that zone then connect your services. The two changes therefore have different effects.
Choose based on your provider’s instructions
If you receive A, AAAA, CNAME or TXT values, you can generally keep the current nameservers and edit the relevant records. DNS stays with the same service.
If the provider requires delegation of the entire zone, change nameservers. First prepare the complete zone with that provider, including email and service verification.
Prepare the destination before switching
Changing nameservers does not automatically copy existing records. Compare both zones and confirm the new DNS service will remain active. Do not end the old service too early.
- Save the current list and values needed for rollback.
- Recreate website, email and verification connections.
- Use only the nameservers actually assigned by the new provider.
- Check DNSSEC with both services before confirming delegation.
Handle DNSSEC as a separate step
DNSSEC lets validating resolvers authenticate DNS answers. Its configuration connects the zone and registry through keys and a DS record. An old DS reference incompatible with the new zone can prevent resolution.
If DNSSEC is active or its state is unknown, request an assisted plan. Do not delete keys or DS data at random or assume a new nameserver list ensures continuity.
Check after the change
Test the domain, www and email from different connections where possible. Caches may still return the old delegation during transition.
With external nameservers, make future DNS changes with their provider. Registration can remain at frdomain.fr; transferring registration is a separate operation.
