NAME
       networkctl - Query or modify the status of network links

SYNOPSIS

       networkctl [OPTIONS...] COMMAND [LINK...]

DESCRIPTION
       networkctl may be used to query or modify the state of the network links as seen by systemd-networkd. Please refer to systemd‐networkd.service(8) for an introduction to the basic concepts, functionality, and
       configuration syntax.

COMMANDS
       The following commands are understood:

       list [PATTERN...]
           Show a list of existing links and their status. If one or more PATTERNs are specified, only links matching one of them are shown. If no further arguments are specified shows all links, otherwise just the specified
           links. Produces output similar to:

               IDX LINK         TYPE     OPERATIONAL SETUP
                 1 lo           loopback carrier     unmanaged
                 2 eth0         ether    routable    configured
                 3 virbr0       ether    no-carrier  unmanaged
                 4 virbr0-nic   ether    off         unmanaged

               4 links listed.

           The operational status is one of the following:

           missing
               the device is missing

           off
               the device is powered down

           no-carrier
               the device is powered up, but it does not yet have a carrier

           dormant
               the device has a carrier, but is not yet ready for normal traffic

           degraded-carrier
               for bond or bridge master, one of the bonding or bridge slave network interfaces is in off, no-carrier, or dormant state

           carrier
               the link has a carrier, or for bond or bridge master, all bonding or bridge slave network interfaces are enslaved to the master

           degraded
               the link has carrier and addresses valid on the local link configured

           enslaved
               the link has carrier and is enslaved to bond or bridge master network interface

           routable
               the link has carrier and routable address configured

           The setup status is one of the following:

           pending
               udev is still processing the link, we don't yet know if we will manage it

           initialized
               udev has processed the link, but we don't yet know if we will manage it

           configuring
               in the process of retrieving configuration or configuring the link

           configured
               link configured successfully

           unmanaged
               networkd is not handling the link

           failed
               networkd failed to manage the link

           linger
               the link is gone, but has not yet been dropped by networkd

       status [PATTERN...]
           Show information about the specified links: type, state, kernel module driver, hardware and IP address, configured DNS servers, etc. If one or more PATTERNs are specified, only links matching one of them are
           shown.

           When no links are specified, an overall network status is shown. Also see the option --all.

           Produces output similar to:

               ●        State: routable
                 Online state: online
                      Address: 10.193.76.5 on eth0
                               192.168.122.1 on virbr0
                               169.254.190.105 on eth0
                               fe80::5054:aa:bbbb:cccc on eth0
                      Gateway: 10.193.11.1 (CISCO SYSTEMS, INC.) on eth0
                          DNS: 8.8.8.8
                               8.8.4.4

           In the overall network status, the online state depends on the individual online state of all required links. Managed links

Title: networkctl - Query or modify the status of network links
Summary
The `networkctl` command is used to query or modify the state of network links managed by `systemd-networkd`. It allows users to list links with their operational and setup status, and to show detailed information about specific links, including their type, state, IP addresses, DNS servers, and more. The tool also provides an overall network status, indicating whether the network is online based on the individual states of managed links.
