It's technically closer to a DHCP/DHCP6/RA thing, but it's not a glibc
thing exclusively. It's implemented in all the major OSes.

mDNS/Avahi/Zeroconf is primarily broadcast traffic. It shouldn't
conflict with a local DNS zone (as in it's not real DNS) *provided that*
you don't have DNS resolution via Avahi enabled (i.e. if "mdns" is in
the "hosts" entry for /etc/nsswitch.conf typically). But services
running on the local machine may still be "weird" if you try to access
them locally. It's generally safer and easier, especially for a
multi-platform/OS environment/network, to just use something like
"home.lan" or the like, though.
