Requirements

Instructions

Who is concerned?

This change can impact customers who:

  • Have defined a custom DNS server name in the DNS records of type NS of their DNS zone, and have associated an IP address of an OVHcloud DNS server with this name via a DNS record of type A.
  • Have also configured a GLUE record for this custom name, in order to associate it with the IP address of an OVHcloud DNS server, in the configuration of the domain name's DNS servers.
  • Are currently using this custom name as their domain name's DNS server (defined in their Control Panel or at their registrar).

For more information, please read our guide on Customizing a domain name's DNS servers (Glue Records).

WARNING

If you have not made any manual changes to the DNS configuration (default setting), you will not be affected by this change.

What can I do if I am concerned?

  1. Determine if you are still using an old IP address in your DNS zone.
  2. Replace it with the new IP address (see the table below).
  3. Update your GLUE records if you have configured one in your OVHcloud Control Panel.
