Probe and Announce queries on MDNS

mDNS
retag add tags

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
