Hi,

What is the purpose of mDNS ?
"zero-configuration networking" seems to be the search term
eg - https://en.wikipedia.org/wiki/Bonjour_(software)

 It seems to be for multicast?
no, it _uses_ multicast.

<rant> when  did "utilize" replace "use"? </rant>

It didn't. According to https://grammarist.com/grammar/use-vs-utilize/, they have similar but distinct meanings. The clearest explanation appears to be this paragraph: "Use the word utilize when you are using something beyond its original and intended purpose. You may use a bat to play baseball, but you can utilize it as a self-defense tool. "

So, in technical terms, saying that "application X utilizes Y" could actually be seen as disparagement. mDNS "uses" multicast networking because multicast networking is a general-purpose tool. But to say that mDNS utilises multicast networking would seem to suggest that the developers of mDNS had to work around the design of multicast networking - that they had to work against multicast.
