I'm not sure how broken a setup without a host IP address entry can be said to be, but it is probably not to your advantage if you're going to run things in Wine. Possibly rpcrt4 could be modified not to depend on a computer name, but I don't know if it's worthwhile. I'll go ahead and resolve this as INVALID.
Well, on friend's computer with Arch and without this lines everything works. And I have suspicious: my setup is uncommon, I use Artix (which is doesn't use systemd), I use Unbound (maybe something related?). So, yeah, I think it either very low chance this bug will occurs on "common" setup or I'm the only one with this bug.
