(Just found this post while researching a problem I’m having)
I’ll echo this request. My use case is a work network that blocks multicast for security reasons. I can connect my Raspberry Pi with Roon Bridge to the network just fine, but my Roon Core on my laptop can’t discover it. With direct IP configurability (like exists for HQPlayer, which doesn’t have native discoverability) I could manually add the Roon Bridge as an end point.
All that being said, I don’t know if the actual audio streaming also relies on multicast (to support the multi-zone playback feature), or if it is point to point. If the former, obviously there would still be an issue even after you bypass discoverability
