OVH Guides

What are the IP addresses of the OVH monitoring ?

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


The monitoring service allows OVH 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 OVH technical teams.

OVH 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 OVH monitoring, it is necessary to authorize the IPs that you will find below.

To do this, you must have :

  • An OVH product on which you have installed a Firewall.
  • Have access to the Firewall rules.

IP to be authorized

Reverse IP Protocol
mrtg-rbx-100 icmp
mrtg-sbg-100 icmp
mrtg-gra-100 icmp
mrtg-bhs-100 icmp
mrtg-rbx-101 icmp
mrtg-rbx-102 icmp
mrtg-rbx-103 icmp
mrtg-gra-101 icmp icmp icmp icmp icmp icmp icmp icmp icmp icmp icmp icmp ( is the server ip) icmp ( 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
