Hi Matt, Thanks for your response. I have since been able to implement your second suggested approach that consists in receiving all the mDNS traffic and parsing the packets myself. This is working well in the Simulator. In parallel of this, I have applied for the Multicast Entitlement, as per your suggestion, however I have received a response last night, and my application has been rejected, with the following comment: "It is currently not our policy to enable this entitlement for apps trying to use mDNS directly. If you need new Bonjour APIs, please work with Matt to file the correct enhancement request." Would you be able to bring this up to the Bonjour API team ? Best regards
