[torqueusers] Status Check request from unknown hosts

[Beob Kyun Kim]

Hi,

I open them only to my worker nodes.
Of course, 32.247.167.0 is not included in my worker nodes.

I tried to block those ip addresses (32.247.167....) with hosts.deny &
iptables.

When we check traffic related to 32.247.167.., the only related things are
DNS lookup to DNS service.

Thanks.
