how come? how does DNS (after all, a central service in the internet)
work with this assumption?

UDP works fine with as a challenge/response system (less so as
client/server, given that there is no notion of a "connection"), and
for responses you need o be able to send messages somewhere.

for whatever reasons, many hardware manufacturers have the idea that
sending/receiving on the *same* port is a good idea.
