Change a domain's nameservers

A domain's nameservers decide which DNS provider answers for it. Change them when you move the domain's DNS to another provider, or back to Coritan. This page covers domains registered with Coritan; for a domain registered elsewhere, change its nameservers at that registrar.

• The registration must be active (Statuses).
• Make sure the new provider already holds the domain's records. Resolvers follow the new nameservers as soon as they see them.
• To use Coritan's DNS, the domain needs a zone on Coritan. The DNS zone row of the Registration card says Hosted here when it has one. If it does not, add the domain as an existing domain first.

1. In the dashboard, go to Websites, open the domain and select the Settings tab.
2. In the Nameservers card, select Edit nameservers.
3. Change the nameservers:
   • Type over a nameserver to replace it, such as ns1.example.net.
   • Select Add nameserver to add another, up to 13.
   • Select the remove button beside a nameserver to take it off the list. The card keeps at least two.
4. Select Save nameservers.

To go back to Coritan's DNS, enter ns1.coritan.com to ns8.coritan.com.

The dashboard confirms that the nameservers are saved, and the card lists the new set. Resolvers keep the old nameservers until their cached answers expire. Check what the registry now publishes from a terminal:

dig NS example.com +short

Once the domain points elsewhere, the records on its DNS tab no longer answer for it, and neither do Coritan's load balancers and proxied records for its names.

Enter at least two nameservers., Enter at most 13 nameservers. or Fill in every nameserver, or remove the empty ones.

A domain takes 2–13 nameservers, and none of them can be empty.

Registration not found

The registration is not active. See Statuses.

Failed to update nameservers: …

The registry refused the change or did not answer. Check that each name is a working nameserver, then try again.
