Finding your Mac's IP address takes less than thirty seconds whether you need it to set up a network printer, troubleshoot a slow connection, or configure local file sharing. Your Mac uses two distinct numerical identifiers: a local network address assigned by your home router and a public address visible to websites across the internet.
Knowing how to locate both numbers quickly saves you time and cuts through unnecessary tech clutter. Below are the exact methods to find your local and public IP addresses using built-in macOS tools, along with practical troubleshooting steps for common connection hiccups.
Understanding Your Mac IP Addresses
Before jumping into the steps, it helps to know what you're looking at. Your network configuration splits into two main categories.
- Local IP Address (LAN): Issued by your router via DHCP, this address lets your Mac communicate with other devices inside your private network, like wireless printers, NAS drives, or smart home hubs. It usually starts with numbers like 192.168 or 10.0.
- Public IP Address: Assigned by your Internet Service Provider (ISP), this is the single address that external servers see when you browse the web. Every device on your home network shares this external identifier.
Method 1: Using System Settings
The most straightforward way to view your local network configuration on modern versions of macOS is through the System Settings app. No command line required. To read more about the context of this, Associated Press offers an informative summary.
- Click the Apple logo in the top-left corner of your screen and select System Settings.
- Scroll down the left sidebar and click on Network.
- Click your active connection, labeled Wi-Fi or Ethernet, depending on how you're plugged in.
- Click the Details button next to your connected network name.
- Select TCP/IP from the menu on the left side of the popup window.
Your local IPv4 address appears clearly next to the IP address field. You can also view your router's gateway address right below it, which helps if you ever need to log into your router's admin dashboard.
Method 2: Using the Terminal App
If you prefer keyboard shortcuts or want to pull network data quickly while scripting or troubleshooting, the built-in Terminal app offers instant results.
- Press Command + Space to open Spotlight search, type
Terminal, and hit Enter. - To find your Wi-Fi IP address, type the following command and press Enter:
ipconfig getifaddr en0 - To find your Ethernet IP address if you're plugged in via a cable, use:
ipconfig getifaddr en1
The terminal instantly returns a single numerical string representing your active local network address.
How to Find Your Public IP Address
Your Mac doesn't store your public IP address locally because your router handles external routing. To find out what the outside world sees, you can query a lightweight external text service directly from your terminal or browse to a lookup page.
Open Terminal and run any of these quick commands:
curl ifconfig.mecurl icanhazip.comcurl ipinfo.io/ip
Each command queries a public endpoint and prints your exact public IPv4 or IPv6 address directly onto your screen. You can also check details like your general geographic region and internet provider via trusted registries like ARIN if you are investigating network routing behavior.
Common Mistakes and Troubleshooting
When looking up network details, users often run into a few predictable roadblocks. Here is how to fix them.
- The 169.254.x.x Address: If your Mac displays an IP address starting with 169.254, it means it failed to receive a valid assignment from your router. This self-assigned link-local address means you have no active internet connection. Try toggling your Wi-Fi off and on, or restart your router.
- Confusing Local and Public: Giving a friend your local address (like 192.168.1.15) won't let them connect to your machine from outside your home network. Always use your public IP address for external connections.
- VPN Interference: If you run a Virtual Private Network, your public IP address reflects the VPN server's location rather than your actual ISP location. Turn your VPN off temporarily if you need to check your true home connection stats.
Frequently Asked Questions
Can my local IP address change randomly?
Yes. Most home routers use DHCP, which means they lease IP addresses to devices dynamically. Your Mac might get a slightly different number after restarting your router or reconnecting to the Wi-Fi after a trip.
How do I assign a static IP address on my Mac?
Go to System Settings > Network > Wi-Fi > Details > TCP/IP, change Configure IPv4 from Using DHCP to Manually, and enter your desired static address along with your subnet mask and router details. Ensure the chosen address falls outside your router's automatic DHCP reservation range to prevent conflicts.
Does my Mac have both an IPv4 and IPv6 address?
Yes, modern versions of macOS support both protocols simultaneously. Your IPv4 address uses standard dotted-decimal notation, while your IPv6 address uses a much longer alphanumeric format separated by colons.
Why do public IP address lookup tools show different locations?
Public geolocation databases rely on registry data provided by ISPs. Because ISPs often route blocks of IP addresses regionally rather than down to your exact neighborhood, geolocation lookups often point to a regional hub city rather than your actual physical street address.
