How to find internal and external IP addresses on Mac OS X and macOS?

An IP (Internet Protocol) address is assigned whenever your device connects to the Internet or a local network. The most frequent form of an IP address is four sets of digits with three digits per set. If your computer is connected to both a local network and the Internet, it will have an internal IP address signed by a local network and external IP address, which is the address of your Internet connection.

If you are setting up a network or sharing files, the IP address is required. In this article, we show a number of ways to find a Mac IP address. This guide applies to any version of Mac OS.

Find your internal IP Address through System Preferences

The first method, which will work on any operating system version, is to visit Network configuration in System Preferences. Open the Mac system preferences and locate Network, click on the network you are connected to, and below the Status line you will see your IP address.

Find out your internal IP address by using Terminal

Nov 21, 2010 Knowing your Mac’s IP address is important for setting up a network or sharing files, here’s two different ways to find your IP address in Mac OS X; an easy way through the GUI and a more technical approach with the command line. These methods will be the same whether you are connected via ethernet or wireless. Jul 25, 2001 I'm new user of OS X and I don't know Unix a lot so I think someone of you can help me. I there something like win command 'ipconfig' in OSX? Does OS X support Dynamic DNS?(client side) Insertin it manually Dns works well but OSX dind't register automatically to it (win 2000 server) Thanks. Ipconfig /all shows the description of each network connection along with additional information such as your physical (MAC) address, DHCP connections, Lease times, as well as in-depth IPv6.

This method is easier and faster for Mac users who are familiar with a command line program called Terminal. Even if you have not used Terminal before, just follow the instructions and you will find the internal IP address. First, use spotlight by pressing Command and Spacebar and type Terminal. Then, press Return. Alternatively, you can find Terminal under the Utilities folder. Open finder, choose Applications, select Utilities, and then launch Terminal.

When Terminal has launched, type the following command: ipconfig getifaddr en0 (to find your IP address if you are connected to a wireless network) or ipconfig getifaddr en1 (if you are connected to an Ethernet). If you are using Mac OS X, the command ipconfig grep inet displays detailed information about your computer signification in the network. The IP address is usually displayed beside last inet, however, this command does not work on macOS High Sierra.

Find your external IP address

To find your external IP address, there are two easy methods that work on all versions of the Mac operating system. First, open Google and Type IP in search. This will display your external address.


If you can browse the Internet, use the Mac command line. Launch Terminal, which is under the Utilities folder, and type: curl ifconfig.me or curl ipecho.net/plain ; echo. These commands will display your IP address in Terminal.

Mac OS X ipconfig

If you momentarily forget where you are at a Mac OS X terminal session, you might type 'ipconfig /all' or something equally Windowish. You will get a response:

Ipconfig

usage: ipconfig <command> <args>>
where <command> is one of waitall, getifaddr, ifcount, getoption, getpacket, set, setverbose

What's this? You already know you mistyped: on Mac OS X you probably meant to run 'ifconfig -a' just as you would on Linux. But 'ipconfig' is different, and is actually something good to have in your bag of tricks.

The first thing ipconfig can do for you is quickly give you all your dhcp info:

$ ipconfig getpacket en0
op = BOOTREPLY
htype = 1
flags = 0
hlen = 6
hops = 0
xid = 1045997387
secs = 0
ciaddr = 0.0.0.0
yiaddr = 192.168.9.30
siaddr = 0.0.0.0
giaddr = 0.0.0.0
chaddr = 0:16:cb:8d:38:f7
sname =
file =
options:
Options count is 7
dhcp_message_type (uint8): ACK 0x5
subnet_mask (ip): 255.255.255.0
lease_time (uint32): 0x93a80
router (ip_mult): {192.168.9.254}
domain_name_server (ip_mult): {192.168.9.254}
server_identifier (ip): 192.168.9.254
end (none):

There are shortcuts to the items listed under 'options':

$ ipconfig getoption en0 router
192.168.9.254
$ ipconfig getoption en0 domain_name_server
192.168.9.254

'ipconfig getifaddr en0' is a quick way to just get the ip address.You can also use ipconfig with its 'set' options to change an interface from DHCP to manual or vice-versa. That's temporary; it doesn't write any start up files.

If you are having difficulty with DHCP, ipconfig has one more use: you can (as root) set verbose logging with 'ipconfig setverbose 1'. With that set, you get minor debugging info written to syslog (/var/log/system.log on my system), but you also get a separate BOOTP/DHCP log in /var/log/com.apple.IPConfiguration.bootp that shows the full BOOTREQUEST/BOOTREPLY packet negotiation.

Think of ipconfig the next time you are looking for DHCP info on a Mac.
