I can tell you definitely though that this is easily accessible via "resolvectl domain <iface>" from the command line and from .network networkd configuration files. > How does systemd-resolved figure out what domains "should" be sent to a given > connection's DNS server without some arcane incantation from the systemd docs? As mentioned elsewhere: 1) Search domains are implicitly routing domains: if an interface has "redhat.com" as search domain we also use that as routing domain, i.e. all *.redhat.com lookups will go to this interface and not to others. 2) If neither search domains nor routing domains are configured on any interface for a domain, lookups are routed to all interfaces in parallel, and the first positive and last negative answer is used. i.e. focus is primarily on "let's make DNS work" and "let's make the best of the little information we traditionally have", and any further, more complex routing requires additional configuration in NM, networkd or directly with resolvectl commands.
