\"Get<\/p>\n

How many commands you know to get IP address on your Linux systems? In this article, we’ll discuss a few ways to get IP address as well as public IP on Linux.<\/p>\n

    \n
  1. ifconfig command<\/a><\/li>\n
  2. ip addr<\/a><\/li>\n
  3. Hostname -I command<\/a><\/li>\n
  4. nmcli command<\/a><\/li>\n
  5. ip route <\/a><\/li>\n
  6. Graphical Method<\/a><\/li>\n
  7. Display Public IP address<\/a><\/li>\n<\/ol>\n

    1) ifconfig command<\/h2>\n

    ifconfig is short for interface configuration. It’s a widely used command line tool used for configuration & viewing of ip addresses, and enabling\/disabling network interfaces.<\/p>\n

    Note: ifconfig command is deprecated, try using ip command.<\/p>\n

    ifconfig \/ ifconfig -a<\/h3>\n

    ifconfig with no arguments will display statistics of all active interfaces. This is the same as running ifconfig -a<\/p>\n

    Example<\/p>\n

    ifconfig<\/p>\n

    Output<\/p>\n

    eth0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
    \n ether a0:2b:b8:22:0c:6b txqueuelen 1000 (Ethernet)

    \n TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 <\/p>\n

    ifconfig <\/h3>\n

    To get an IP address of a specific network interface, run ifconfig followed by an interface name<\/p>\n

    Example<\/p>\n

    ifconfig eth0<\/p>\n

    Output<\/p>\n

    wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
    \n inet 192.168.43.156 netmask 255.255.255.0 broadcast 192.168.43.255
    \n inet6 fe80::9ed2:1eff:fe31:3fb9 prefixlen 64 scopeid 0x20
    \n ether 9c:d2:1e:31:3f:b9 txqueuelen 1000 (Ethernet)

    \n RX errors 0 dropped 0 overruns 0 frame 0
    \n TX packets 62046 bytes 8082927 (7.7 MiB)
    \n TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 <\/p>\n

    2) ip addr<\/h2>\n

    ip addr is yet another command you can use to get an IP address of a system and other interface statistics<\/p>\n

    Example<\/p>\n

    ip addr<\/p>\n

    Output<\/p>\n

    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    \n link\/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    \n inet 127.0.0.1\/8 scope host lo
    \n valid_lft forever preferred_lft forever
    \n inet6 ::1\/128 scope host
    \n valid_lft forever preferred_lft forever
    \n2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
    \n link\/ether a0:2b:b8:22:0c:6b brd ff:ff:ff:ff:ff:ff
    \n3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    \n link\/ether 9c:d2:1e:31:3f:b9 brd ff:ff:ff:ff:ff:ff

    \n inet6 fe80::9ed2:1eff:fe31:3fb9\/64 scope link noprefixroute
    \n valid_lft forever preferred_lft forever <\/p>\n

    3) Hostname -I command<\/h2>\n

    To get the IP address of active network connections, run<\/p>\n

    hostname -I<\/p>\n

    Output<\/p>\n

    192.168.43.156<\/p>\n

    4) nmcli command<\/h2>\n

    nmcli – Network Manager command Line interface – is a command line tool used for creating, editing, displaying, deleting, activating and deactivating connections.<\/p>\n

    nmcli<\/h3>\n

    Example<\/p>\n

    nmcli<\/p>\n

    Output<\/p>\n

    \n
    \nDNS configuration:
    \n servers: 192.168.43.1
    \n interface: wlan0
    \n
    \nUse “nmcli device show” to get complete information about known devices and
    \n“nmcli connection show” to get an overview on active connection profiles. <\/p>\n

    nmcli device show<\/h3>\n

    To get the IP address and even more detailed statistics, run<\/p>\n

    nmcli device show<\/p>\n

    Output<\/p>\n

    GENERAL.DEVICE: wlan0
    \nGENERAL.TYPE: wifi
    \nGENERAL.HWADDR: 9C:D2:1E:31:3F:B9

    \n – <\/p>\n

    5) ip route get 1.2.3.4 | awk ”<\/h2>\n

    This is yet another command that can be used to get an IP address without much statistics<\/p>\n

    ip route get 1.2.3.4 | awk ”<\/p>\n

    Output<\/p>\n

    192.168.43.156<\/p>\n

    6) Network Settings in Graphical User Interface<\/h2>\n

    If you are running Linux in a graphical environment, you can easily navigate to the Network settings and check out the IP address. In this example, we have demonstrated this using Ubuntu 18.04 GNOME interface.<\/p>\n

      \n
    1. Click on the Network icon as shown.
      \"get<\/li>\n
    2. On the pull-down menu that appears, be sure to locate the connected network interface. In this case, it’s the wired connection and we can see that the interface is up by ‘Wired connected’ status. Click on it.
      \"get<\/li>\n
    3. Next, click on the ‘Wired settings’ option that appears below
      \"get<\/li>\n
    4. This displayed a ‘Network Settings’ window. Click on the gear icon next to the ON\/OFF toggle and a pop-up Window will appear showing the IP details of the connected network interface.
      \"get<\/li>\n<\/ol>\n

      Display a Public IP address of your Linux System<\/h2>\n

      If you wish to get the Public IP of your Linux System, the following commands come in handy<\/p>\n

      curl ipinfo.io\/ip
      \n
      \ncurl ifconfig.me
      \n
      \ncurl bot.whatismyipaddress.com
      \n
      \ndig +short myip.opendns.com @resolver1.opendns.com
      \n
      \ncurl checkip.dyndns.org
      \n
      \ncurl ident.me
      \n
      \nhost myip.opendns.com resolver1.opendns.com
      \n
      \ncurl ipecho.net\/plain <\/p>\n

      Do you know any other method to get the IP address? Please reply with your comments.<\/p>\n
