57 <title>Description</title>
58
59 <para><command>systemd-resolved</command> is a system service that
60 manages network name resolution. It implements a caching DNS stub
61 resolver and an LLMNR resolver and responder. It also generates
62 <filename>/run/systemd/resolve/resolv.conf</filename> for
63 compatibility which may be symlinked from
64 <filename>/etc/resolv.conf</filename>.</para>
65
66 <para>The DNS servers contacted are determined from the global
67 settings in
68 <citerefentry><refentrytitle>resolved.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry>,
69 the per-link static settings in <filename>.network</filename>
70 files, and the per-link dynamic settings received over DHCP. See
71 <citerefentry><refentrytitle>systemd.network</refentrytitle><manvolnum>5</manvolnum></citerefentry>
72 for more details.</para>
73
74 <para>Note that
75 <filename>/run/systemd/resolve/resolv.conf</filename> should not
76 be used directly, but only through a symlink from
77 <filename>/etc/resolv.conf</filename>.</para>
