With the ip command, you can adjust the way a Linux computer handles IP addresses, network interfaces
controllers (NICs), and routing rules. The changes also take immediate effect—you don’t have to reboot.
Address <===> IP addresses and ranges.
Link <===> Network interfaces, such as wired connections and Wi-Fi adapters.
Route <===> The rules that manage the routing of traffic sent to addresses via interfaces (links).
ip a
<===> Shows addresses assigned to all network interfaces // To show the IP addresses assigned to an interface on your server // Shows and manipulates routing, devices, policy routing and tunnelsip addr
<===> to sameip addr show
<===> to sameip address show
<===> to same
ip address add 192.168.1.254/24 dev enps03
<===> To assign an IP to an interface, for example, enps03
ip address del 192.168.1.254/24 dev enps03
<===> delete an IP on an interface
ip neigh
<===> Shows the current neighbour table in kernelip neighbour show
<===> Ukáže všechny zařízení v síti
ip link
<===> can add and remove bridges and set their options.
ip link set eth0 up
<===> nahodi rozhrani eth0 // Bring up interface eth0
ip link set eth0 down
<===> shodi rozhrani eth0 // Bring down interface eth0
ip route
<===> zobrazi IP gateway, DNS // Show table routes.ip route show
<===> print the routing table
ip link show
<===> ukaze rozhrani - asi zkracena verzeip -br link show
<===> -br switch prints this output in a much more readable table format
ip -4 addr
<===> Display Only IPv4 Addressesip -6 addr
<===> Display Only IPv6 Addresses
ip addr show dev lo
<===> Display Information for a Single Interface
LOWER_UP <===> is a physical layer link flag (the layer below the network layer, where IP is generally located).
LOWER_UP <===> indicates that an Ethernet cable was plugged in and that the device is connected to the network.
LOWER_UP differs from UP, which additionally requires the network interface to be enabled.
NO-CARRIER <===> network interface didn't get any IP
BROADCAST <===> This interface supports broadcasting
MULTICAST <===> This interface supports multicasting
LOOPBACK <===> This is a loopback interface
state UNKNOWN <===> This can be DOWN (the network interface is not operational), UNKNOWN (the network interface is operational but nothing is connected), or UP (the network is operational and there is a connection).
scope host <===> The IP address scope. This IP address is only valid inside the computer (the “host”).
state UP <===> The interface is operational and connected.
UP <===> interface is UP (operational and connected)
