It implements a caching DNS stub resolver and an LLMNR resolver and responder. It also generates /run/systemd/resolve/resolv.conf for compatibility which may be symlinked from /etc/resolv.conf. The DNS servers contacted are determined from the global settings in resolved.conf5, the per-link static settings in .network files, and the per-link dynamic settings received over DHCP. See systemd.network5 for more details. Note that /run/systemd/resolve/resolv.conf should not be used directly, but only through a symlink from /etc/resolv.conf. resolved.conf5, systemd1, systemd.network5, systemd-networkd.service8
