Fun fact, DNS errors

Hello,

If you see DNS errors on a HOST, and start tracing to get the perpetrator. It could be that you discover that OneAgent is trying to connect to an ActiveGate that is not available on the current network (-; 

Then you know your time has come to implement "Network Zones":

Oneagent does IPV6 queries, does anybody know how to turn this off?

I believe this is due to the OS itself, configured to support IPv6. Depending on your case you can configure the ActiveGate to announce only IP address instead of hostname. The OneAgents won't resolve the hostname.

Hello @henk_stobbe. You can deactivate the IPv6 stack if you are not using it inside your network.

The true delight is in the finding out rather than in the knowing.

If you don't have IPv6 connectivity, disabling it is the best thing you can do 🙂
