Shameless plug: When I read about SSDP a little while ago I was curious to see if I'd encounter it on many networks. As I was also trying to learn Swift/Apple development, I've written two (non-free) little apps for macOS/iOS to monitor SSDP messages:

Ever since creating it and just checking on some networks, I'm surprised of how many devices are actually using it. I probably saw this in Wireshark before as well, but probably overlooked it because you're never really looking for it. I wonder if many other such protocols are often used but easily missed...
