I know you can do ifconfig | grep inet, but that shows you several IPv4 addresses. How do I get the specific one for SSHing et al?

  • What you are looking for is not your Mac IP address but the public IP address your ISP attributed to the Internet interface of your router.

    You should either clarify your question, i.e. you want to know internal IP in your local network or change the accepted answer, because none of the answers give you an option to get an external IP, but a few comments do.

  • @alturium you should make it an answer, because it IS the answer to the question. Just add a command to get internal IP as well.

Use ipconfig getifaddr en1 for wireless, or ipconfig getifaddr en0 for ethernet.

ipconfig getifaddr en0 is default for the Wi-Fi network adapter.

Alternatively you can also do:

dig -4 TXT +short o-o.myaddr.l.google.com @ns1.google.com

Output, e.g.:
  • 20
    This shows my internal (to my router) IP address (e.g. 192.168.1.xxx), not the external IP address. (As do most of the other answers below.) May 5, 2015 at 22:38

    It has changed for years, 'ipconfig getifaddr en0' is default for wifi interface Jan 31, 2017 at 16:35

The following works for me on 10.8 and on 10.10 Yosemite.

ifconfig | grep "inet " | grep -Fv | awk '{print $2}' 

If you find the above gives you more than one answer, save the following to a script, and run it instead


#!/usr/bin/env bash

  IT=$(ifconfig "$1") 
  if [[ "$IT" != *"status: active"* ]]; then
  if [[ "$IT" != *" broadcast "* ]]; then
  echo "$IT" | grep "inet " | grep -v | awk '{print $2}'

  # snagged from here: https://superuser.com/a/627581/38941
  DEFAULT_ROUTE=$(route -n get 2>/dev/null | awk '/interface: / {print $2}')
  if [ -n "$DEFAULT_ROUTE" ]; then
    dumpIpForInterface "$DEFAULT_ROUTE"
    for i in $(ifconfig -s | awk '{print $1}' | awk '{if(NR>1)print}')
      if [[ $i != *"vboxnet"* ]]; then
        dumpIpForInterface "$i"

    Can confirm this solution works great. I have multiple interfaces all with valid local IPs, but this solution properly returns the IP for the primary interface (that is, the interface used to route traffic to the wider net)

I've got this set up in an .aliases dotfile for frequent ip lookup:

alias ip="dig +short myip.opendns.com @resolver1.opendns.com"
alias localip="ipconfig getifaddr en0"
  • For me, the localip option there doesn't work anymore, but this does: ifconfig | grep "inet " | grep -Fv | awk '{print $2}'

  • This is the best answer: While dig does reach outside of your machine, it is a domain name resolver, which means its main function is precisely to match domain name to IP address. In this case, it is your own IP address, of course. Mar 8, 2021 at 16:58
  • the ip alias doesn't seem to be working (I'm on OSX Catalina). This one does: curl -s http://ipecho.net/plain; echo

You can do the following:

Type ifconfig or ifconfig -a. This command shows you the list of interfaces along with their IP and MAC addresses (the latter one only if applicable). You can also type ifconfig en0 or ifconfig en1 for the configuration of a particular interface only (as someone said in their answers, en0 is typically the wired Ethernet while en1 is the WiFi interface).

As an alternative, netstat -i will list all interfaces and will show you the IP addresses you have assigned to each of them.

Typically, when you have SSH daemon running on a box, it will listen on all available interfaces, ie. you can use any IP address that's configured on your machine to connect to that machine via SSH (this, obviously, subject to Firewall rules). If you're after what the OS calls a Primary interface and primary IP address, you can use the scutil command like this:

MacBook:~ scutil
> show State:/Network/Global/IPv4
<dictionary> {
  PrimaryInterface : en0
  PrimaryService : C0550F84-5C07-484F-8D62-C8B90DC977D8
  Router :
> show State:/Network/Interface/en0/IPv4
<dictionary> {
  Addresses : <array> {
    0 :
  BroadcastAddresses : <array> {
    0 :
  SubnetMasks : <array> {
    0 :

Please note, that the above, even though is a command-line command, is also interactive (so you run scutil and then enter its own commands into it). The first show command tells you the name of the primary interface for the OS (i.e. this will be the one on top of the list in your System Preferences / Network Preferences window), as well as the IP address of your default router. The second show command takes State:/Network/Interface/<ifname>/IPv4 argument (in this case, en0) and gives you the IP addresses assigned to it. You're looking for the address in the Addresses array, the other two entries are broadcast addresses and the netmasks.

Hope that helps, but if anything is not clear, let me know.

    Thanks for this answer. I wrote a quick script to get the IP your primary interface: echo "show State:/Network/Interface/$(echo 'show State:/Network/Global/IPv4' | scutil | grep 'PrimaryInterface ' | sed 's/ PrimaryInterface : //')/IPv4" | scutil | pcregrep -Mo1 " Addresses : <array> {\n 0 : ([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})"

To find your Mac's current internal IP address, run:

ifconfig -l | xargs -n1 ipconfig getifaddr

This is basically equivalent to ipconfig getifaddr en0, but more reliable! en0 is not always the current network interface!

Thank you to @epylinkn in the comments of another answer for this hint. I'm posting it here so it's more visible; I initially missed it myself.


To get the IP address of your computer facing the Internet, here is a working receipe:

if=`netstat -nr | awk '{ if ($1 ~/default/) { print $6} }'`
ifconfig ${if} | awk '{ if ($1 ~/inet/) { print $2} }'

It should work even when you have multiple interfaces active, even when you have interfaces you don't know which one is actually the default gateway.

    This gets the internal network IP address (eg: 192.168.0.*), not the external one exposed to the internet.

  • Thank you for this feedback. Could you tell me on which version of the OS you are? Could you provide me the output of netstat -nr | grep default ?

  • This gets the IP of the interface that serves in/outbound traffic. If you're behind NAT, that will give your LAN address, not WAN address. But it can be useful for a lot of purposes, and it doesn't reach out for network.

Just for the record, you can make a bash script with the following content which gives you your external IP address

wget -qO - http://ipecho.net/plain; echo

    By default wget is not a part of macOS and needs to be installed from a non-Apple source. Jan 7, 2019 at 9:39
  • Is the question macOS specific ? it is by default installed on many linux distributions.
