+title: "Changing the IP addresses of OVHcloud DNS servers"
+excerpt: "Discover the list of new IP addresses for OVHcloud DNS servers"
+updated: 2025-08-07
+---
+
+## Objective
+
+This guide explains the IP addresses changes affecting part of our DNS servers hosted in Europe, which will apply from **August 2025**.
+
+**Discover the list of new IP addresses for OVHcloud DNS servers.**
+
+## Requirements
+
+- Access to your [OVHcloud Control Panel](/links/manager) to manage the domain name concerned.
+
+## 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)](/pages/web_cloud/domains/glue_registry).
+
+> [!warning]
+>
+> If you have not made any manual changes to the DNS configuration (default setting), you will not be affected by this change.
+
+### Calendar
+
+| Step                                | Estimated date           |
+|------------------------------|------------------------------|
+| Delete IPv6 traffic on old IPs         | Completed on 05 August 2025 |
+| Commissioning of new IPs   | Starting August 5, 2025 |
+| Send the first informational email to the identified customers | Mid-August 2025 |
+| Send second reminder email         | September 15, 2025 |
+| Deletion of IPv4 traffic          | Early October 2025 |
+
+> [!warning]
+>
+> Using old IP addresses after this date will cause DNS resolution failure for domain names whose configuration has not been updated.
+
+### 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](/pages/web_cloud/domains/glue_registry) if you have configured one in your control panel.
