Quick answer
For a domain historically managed at 123-reg.co.uk, edit DNS at the provider that is authoritative now. A registrar account and the active DNS zone can be different systems.
Applies to
For the owner or an authorized editor of the website/account named in this article. Confirm the installed product version and permissions. Interactive Online hosting access does not automatically grant an application administrator login.
Steps
- Identify the current registrar and authoritative nameservers. Save existing website, mail and verification records before changing anything.
- For a record change, edit the intended hostname at the active DNS provider. For a nameserver change, prepare the complete destination zone and update the delegation at the current registrar instead.
- Review the exact host, type, value and TTL, then check authoritative answers and the website/mail behavior after the change. Keep the old service available during the cutover.
Check the result
Verify the intended hostname from the authoritative zone and confirm that mail records and other services remain correct.
Troubleshooting and support
If the historical provider menu is unavailable, use the current provider's instructions. Editing an inactive zone will not fix public DNS, and repeated changes do not bypass cached TTLs.
Contact support from the owning account with the domain, product/version, exact error, time/time zone and redacted evidence. Exclude credentials, session URLs, payment details and private customer records. Confirm any separate application-support scope.
