What are the IP addresses of the OVHcloud monitoring?

Find here the IP addresses to fill in when setting up a firewall so that OVHcloud monitoring will continue to work on your server

Last updated 13th December 2022


The monitoring service allows OVHcloud to monitor the status of your machine and automatically trigger the intervention of a technician in the datacenter.

All the servers of our customers and the entire network are monitored 24/7 by OVHcloud technical teams.

OVHcloud intervenes as soon as an alert (non-response to the pings) is triggered in order to minimize the downtime of the servers and the network.

To implement a restrictive firewall, especially on ICMP, and continue to benefit from OVHcloud monitoring, it is necessary to authorize the IPs that you will find below.


  • An OVHcloud service on which you have installed a firewall
  • Access to the firewall rules


IP addresses to be authorised

proxy.rbx.ovh.net icmp
proxy.sbg.ovh.net icmp
proxy.bhs.ovh.net icmp
ping.ovh.net icmp
proxy.ovh.net icmp
xxx.xxx.xxx.250 (xxx.xxx.xxx.aaa is the server ip) icmp
xxx.xxx.xxx.251 (xxx.xxx.xxx.aaa is the server ip) icmp + Port monitored by the monitoring service

Communication between the RTM service and your server also requires that you allow inbound and outbound connections on UDP ports 6100 through 6200.

If your server is located in Roubaix 3, you have to retrieve the last IP via tcpdump.

 root@nsXXXX:# tcpdump host server.ip | grep ICMP 

Server monitoring

Log in to the OVHcloud Control Panel and select the Bare Metal Cloud tab. Select the server concerned in the Dedicated servers menu.

You can set the monitoring status for a dedicated server from the General information tab (section Service status).


Click on the button Configure. In the popup window, you have three options for the monitoring behaviour:

  • Disabled: This option stops alert messages and interventions by OVHcloud. Choose this if you are executing pertinent administrative actions on the server which prevent an ICMP response.
  • Enabled with proactive intervention: If the server stops responding, an alert email is sent to you and the server will be checked by a technician.
  • Enabled without proactive intervention: You will receive an alert message by email in case the server stops responding. To initiate an intervention, you will need to create a support request.


Click on Confirm to update your monitoring configuration.

Enabling monitoring for specific services

In addition to standard monitoring, you can authorise OVHcloud to monitor specific services such as HTTP, SSH and other protocols.

In the General information tab, click the ... button next to "Monitored services" in the Service status box. Click Monitor my services.


You will be redirected to the page below. Click Monitor a service, then enter the IP address, protocol, port number, server response, and time interval between your service checks. Click the validation symbol (V) to confirm the changes.
