To update the nameservers for your .DE domain, follow this organized step-by-step guide:

1. Verify DNS Servers with NAST:

   • Use Denic's NAST tool to ensure your current DNS servers meet .DE requirements.
   • Run a scan and generate necessary reports as per instructions from Denic.

2. Prepare Hosting Provider:

   • Confirm that your hosting provider has the zone file ready for your domain.
   • Ensure they can provide authoritative DNS server IPs meeting .DE criteria (distinct, at least one IPv4).

3. Update Nameservers in Domain Control Panel:

   • Log into Esadax's control panel.
   • Navigate to the DNS management section for your domain.
   • Replace or add new authoritative independent DNS server IPs as required.

4. Post-Update Verification:

   • After updating, perform a check using NAST or Esadax's verification tools.
   • Review any error messages and contact support if issues arise.

5. Monitor and Test:

   • Use tools like nslookup or dig to monitor DNS performance post-update.
   • Consider setting up a secondary server for testing before going live.

6. Contact Support if Needed:

   • Reach out to Esadax support for additional assistance or specific instructions.
