title: "Changing the IP addresses of OVHcloud DNS servers"
3+
excerpt: "Discover the list of new IP addresses for OVHcloud DNS servers"
4+
updated: 2025-08-07

## Objective
8+
9+
This guide explains the IP addresses changes affecting part of our DNS servers hosted in Europe, which will apply from **August 2025**.
10+
11+
**Discover the list of new IP addresses for OVHcloud DNS servers.**
12+
13+
## Requirements
14+
15+
- Access to your [OVHcloud Control Panel](/links/manager) to manage the domain name concerned.
16+
17+
## Instructions
18+
19+
### Who is concerned?
20+
21+
This change can impact customers who:
22+
23+
- 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`.
24+
- 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.
25+
- Are currently using this custom name as their domain name’s DNS server (defined in their Control Panel or at their registrar).
26+
27+
For more information, please read our guide on [Customizing a domain name’s DNS servers (Glue Records)](/pages/web_cloud/domains/glue_registry).
28+
29+
> [!warning]
30+
>
31+
> If you have not made any manual changes to the DNS configuration (default setting), you will not be affected by this change.
32+
33+
### Calendar
34+
35+
| Step | Estimated date |
36+
|------------------------------|------------------------------|
37+
| Delete IPv6 traffic on old IPs | Completed on 05 August 2025 |
38+
| Commissioning of new IPs | Starting August 5, 2025 |
39+
| Send the first informational email to the identified customers | Mid-August 2025 |
40+
| Send second reminder email | September 15, 2025 |
41+
| Deletion of IPv4 traffic | Early October 2025 |
42+
43+
> [!warning]
44+
>
45+
> Using old IP addresses after this date will cause DNS resolution failure for domain names whose configuration has not been updated.
46+
47+
### What can I do if I am concerned?
48+
49+
1. Determine if you are still using an old IP address in your DNS zone.
50+
2. Replace it with the new IP address (see the table below).
51+
3. [Update your GLUE records](/pages/web_cloud/domains/glue_registry) if you have configured one in your control panel.
52+
53+
### IP address mapping table
