I'm wondering about one thing, now that I've read a few "may cause issues" and "is used for mDNS" replies: what the F is mDNS actually doing in the background?

Is it really going to assign "lancelot.roundtable.local" to my washing machine on a whim, which leaves the microwave unresolvable?

Can't I instruct the mDNS server running on my machine to respond to a particular name ending in .local?

Can't eg. dnsmasq insert itself into a conversation on 224.0.0.251 saying "Let me answer this question" for certain queries?

I'm a little fuzzy on this, but my understanding is that for mDNS to be reliable it is required that all .local hosts implement mDNS to allow for conflict resolution.

If you’ve set up x.local in your DNS for your dryer but your laptop uses mDNS, it’s possible that your lapatop’s mDNS will get a response from your microwave that it’s reachable at x.local. The solution (not an expert, please check this) is to set up the dryer in DNS as x.domain-thar-you-own or x.home.arpa
