Hello there, Beginner here. OPC UA makes use of mDNS to advertise its services on the local network. However, from what I have read about MDNS, there is a probe and announcement query during every bootup, or sleep event.

But, when i run the server, I see readings continously, after which I see SRV records with cache flush = true. Could you tell me, why cannot wireshark capture probe / announcement queries?

Question may be silly. Please do not mind. Looking forward for the answer.

Regards, Rakshan
