OVH Guide

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.

Requirements

The monitoring service allows 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 an access to the Firewall rules.

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
