I've been playing with discovery of my wiz bulbs this morning, and I've determined that indeed the Mac and IP address don't matter:

$ echo '{"method":"registration","id":5,"params":{"phoneIp":"127.0.0.1","register":false,"phoneMac":"000000000000"}}' | nc -u -w 1 192.168.84.205 38899
{"method":"registration","id":5,"env":"pro","result":{"mac":"444f8e2df7b8","success":true}}

So if you don't want to deal with the complications of this, you don't have to. I still have to figure out actually doing this in broadcast mode, not unicast, though.

you don't have to

Umm :(
.. just did it :)

Well, then I might as well use it :). I updated openhab/openhab-addons#17856

Hi @andrewfg. Thanks for the useful addition.
See my comment below regarding the binary request array.

May I ask you to create a PR in docs repo as well?
