Cherry-pick of PR #9953 to 6.6 branch. Original message:
At the moment, IP addresses collected from a network interfaces have no specific order. What can happen is that even though an interface has both IPv4 and IPv6 addresses, the IPv6 address might be returned first. This matters because the first IP address of the first non-loopback interface will be used in the
message
string, e.g.:"message": "Host vagrant-2016 (IP: 10.0.2.15) restarted"
. The IPv4 address (if it exists) should be easier to read and the more "expected" one for the user.
