Команды (Commands)

query HOSTNAME|ADDRESS...
           Resolve domain names, as well as IPv4 and IPv6 addresses.
           When used in conjunction with --type= or --class= (see
           below), resolves low-level DNS resource records.

           If a single-label domain name is specified it is searched for
           according to the configured search domains — unless
           --search=no or --type=/--class= are specified, both of which
           turn this logic off.

           If an international domain name is specified, it is
           automatically translated according to IDNA rules when
           resolved via classic DNS — but not for look-ups via
           MulticastDNS or LLMNR. If --type=/--class= is used IDNA
           translation is turned off and domain names are processed as
           specified.

       service [[NAME] TYPE] DOMAIN
           Resolve DNS-SD[1] and SRV[2] services, depending on the
           specified list of parameters. If three parameters are passed
           the first is assumed to be the DNS-SD service name, the
           second the SRV service type, and the third the domain to
           search in. In this case a full DNS-SD style SRV and TXT
           lookup is executed. If only two parameters are specified, the
           first is assumed to be the SRV service type, and the second
           the domain to look in. In this case no TXT resource record is
           requested. Finally, if only one parameter is specified, it is
           assumed to be a domain name, that is already prefixed with an
           SRV type, and an SRV lookup is done (no TXT).

       openpgp EMAIL@DOMAIN...
           Query PGP keys stored as OPENPGPKEY resource records, see RFC
           7929[3]. Specified e-mail addresses are converted to the
           corresponding DNS domain name, and any OPENPGPKEY keys are
           printed.

       tlsa [FAMILY] DOMAIN[:PORT]...
           Query TLS public keys stored as TLSA resource records, see
           RFC 6698[4]. A query will be performed for each of the
           specified names prefixed with the port and family
           ("_port._family.domain"). The port number may be specified
           after a colon (":"), otherwise 443 will be used by default.
           The family may be specified as the first argument, otherwise
           tcp will be used.

       status [LINK...]
           Shows the global and per-link DNS settings currently in
           effect. If no command is specified, this is the implied
           default.

       statistics
           Shows general resolver statistics, including information
           whether DNSSEC is enabled and available, as well as
           resolution and validation statistics.

       reset-statistics
           Resets the statistics counters shown in statistics to zero.
           This operation requires root privileges.

       flush-caches
           Flushes all DNS resource record caches the service maintains
           locally. This is mostly equivalent to sending the SIGUSR2 to
           the systemd-resolved service.

       reset-server-features
           Flushes all feature level information the resolver learnt
           about specific servers, and ensures that the server feature
           probing logic is started from the beginning with the next
           look-up request. This is mostly equivalent to sending the
           SIGRTMIN+1 to the systemd-resolved service.

       dns [LINK [SERVER...]], domain [LINK [DOMAIN...]], default-route
       [LINK [BOOL...]], llmnr [LINK [MODE]], mdns [LINK [MODE]], dnssec
       [LINK [MODE]], dnsovertls [LINK [MODE]], nta [LINK [DOMAIN...]]
           Get/set per-interface DNS configuration. These commands may
           be used to configure various DNS settings for network
           interfaces. These commands may be used to inform
           systemd-resolved or systemd-networkd about per-interface DNS
           configuration determined through external means. The dns
           command expects IPv4 or IPv6 address specifications of DNS
           servers to use. Each address can optionally take a port
           number separated with ":", a network interface name or index
           separated with "%", and a Server Name Indication (SNI)
           separated with "#". When IPv6 address is specified with a
           port number, then the address must be in the square brackets.
           That is, the acceptable full formats are
           "111.222.333.444:9953%ifname#example.com" for IPv4 and
           "[1111:2222::3333]:9953%ifname#example.com" for IPv6. The
           domain command expects valid DNS domains, possibly prefixed
           with "~", and configures a per-interface search or route-only
           domain. The default-route command expects a boolean
           parameter, and configures whether the link may be used as
           default route for DNS lookups, i.e. if it is suitable for
           lookups on domains no other link explicitly is configured
           for. The llmnr, mdns, dnssec and dnsovertls commands may be
           used to configure the per-interface LLMNR, MulticastDNS,
           DNSSEC and DNSOverTLS settings. Finally, nta command may be
           used to configure additional per-interface DNSSEC NTA
           domains.

           Commands dns, domain and nta can take a single empty string
           argument to clear their respective value lists.

           For details about these settings, their possible values and
           their effect, see the corresponding settings in
           systemd.network(5).

       revert LINK
           Revert the per-interface DNS configuration. If the DNS
           configuration is reverted all per-interface DNS setting are
           reset to their defaults, undoing all effects of dns, domain,
           default-route, llmnr, mdns, dnssec, dnsovertls, nta. Note
           that when a network interface disappears all configuration is
           lost automatically, an explicit reverting is not necessary in
           that case.

       log-level [LEVEL]
           If no argument is given, print the current log level of the
           manager. If an optional argument LEVEL is provided, then the
           command changes the current log level of the manager to LEVEL
           (accepts the same values as --log-level= described in
           systemd(1)).
