The Basics of Pulling an IP Address: What You Need to Know
When it comes to understanding the internet, knowing how to pull an IP address is a fundamental skill. An IP address (Internet Protocol address) is a unique identifier that is assigned to each device connected to the internet. It is used to identify and locate a device on the network, enabling communication between two or more devices. In this article, we will discuss the basics of pulling an IP address, including what it is, why it’s important, and how to do it.
What is an IP Address?
An IP address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It uniquely identifies each device on the network and allows data packets to be routed from one device to another. An IP address consists of four numbers separated by periods, such as 192.168.1.1.
Why is Pulling an IP Address Important?
Pulling an IP address can be useful in many situations. For example, if you are troubleshooting a network issue or trying to track down malicious activity on your network, you may need to pull an IP address in order to identify the source of the problem or determine which device is responsible for the malicious activity. Additionally, if you are trying to access a website or service that requires authentication, you may need to pull your own IP address in order to gain access.
How Do You Pull an IP Address?
Pulling an IP address can be done in several ways depending on your operating system and what type of information you need. On Windows systems, you can use the ipconfig command in Command Prompt or PowerShell; on Mac systems, you can use the ifconfig command in Terminal; and on Linux systems, you can use the ip command in Terminal. Additionally, there are websites that allow you to look up your public IP address without having to run any commands or install any software.
In conclusion, knowing how to pull an IP address is essential for understanding how networks work and troubleshooting any issues that may arise with them. With this knowledge in hand, you’ll be able to identify devices on your network and access services that require authentication with ease.

How to fix “self-assigned IP address” issue on Mac
Is your MacBook struggling to access the internet, though your Wi-Fi or Ethernet works fine? This can be due to the self-assigned IP error on your Mac. Worry not! In this guide, I’ll share how to fix the internet not working due to a self-assigned IP address error on your Mac to regain a stable network connection.
But before we jump into the troubleshooting steps to resolve the issue, let’s understand what a self-assigned IP error is.
What does “self-assigned IP address” mean on Mac?
The “self-assigned IP address” error on Mac refers to a situation where your device assigns an IP address and sets up an ad-hoc network instead of obtaining one from the network router or DHCP (Dynamic Host Configuration Protocol) server. This self-assigned IP address is not legitimate or acknowledged on the network.
That’s why your Mac cannot connect to the internet or other devices on the network, resulting in limited or no network connectivity. This issue occurs due to network configuration conflicts, DHCP server unavailability, or problems with Mac’s network or Firewall settings.
So, what to do when your Mac has a self-assigned IP address? Continue reading to get rid of the issue and restore standard network functionality on your Mac.
- Check your connection
- Reboot your network devices
- Rejoin your Wi-Fi network
- Check your connection settings
- Reset your Network Preferences on Mac
- Renew DHCP Lease on macOS
- Create a new network location
- Reset the Firewall on your Mac
- Set Service Order from Mac’s network settings
- Change DNS Servers on macOS
- Check for conflicting IP address
- Disable VPN
1. Check your connection
Before diving into Mac-specific settings, ensure that your router is functioning correctly and located near your Mac to obtain a valid IP address. Besides, if you are using an Ethernet connection, plug in the cable snugly.
I also check to validate that the cable has no fault and is in good condition. Moreover, If you are using an old Wi-Fi router, discard it and get a new one to obtain a smoother connection.
2. Reboot your network devices
Restarting both your modem and router can often resolve temporary network glitches. Power off the devices, unplug the cables and wait a few seconds. It will help them cool down, as excessive heat can cause malfunctions. After that, plug all cables, connect them to the power outlet, and turn them back on.
In the meantime, restart your Mac once to iron out any bugs in macOS.
- Click the Apple logo .
3. Rejoin your Wi-Fi network
Sometimes, simply forgetting and rejoining your Wi-Fi network can solve the self-assigned IP address error on your Mac.
- Turn off Wi-Fi for a few seconds and toggle it on.
4. Check your connection settings
Verify that your Mac’s network settings are configured correctly. You must opt for the appropriate network settings to obtain IP addresses and DNS information automatically.
- Go to your Wi-Fi Details . I have shown the steps above.
- Select TCP/IP from the left panel.
You may also try turning off the IPv6, as some users reported it conflicted with the IP address assigning procedure.
- Click on the drop-down arrow beside Configure IPv6 .
5. Reset your Network Preferences on Mac
Resetting the network preferences can help eliminate IP address misconfiguration, causing the internet to not work. So, you must delete specific network connectivity-related files from your MacBook.
- Launch Finder .
- Enter your Mac password to authenticate the deletion.
- Restart your Mac. It will automatically recreate the deleted files.
- Log in and connect to your Wi-Fi network.
- Go to the TCP/IP setting again and check the router files.
6. Renew DHCP Lease on macOS
This method is effective when the assigned IP address may have expired or encountered conflicts. When you renew the DHCP Lease, your Mac requests a new IP address from the DHCP server. It ensures a fresh and valid configuration and resolves connectivity issues.
- Open the same TCP/IP tab window from Wi-Fi Details, as shown above.
After renewing the lease, check if you can connect to your network. If that doesn’t help, try creating a New Network Location and renewing the lease.
7. Create a new network location
Creating a new network location lets your Mac start fresh with network settings and eliminate a self-assigned IP address.
- Click the Apple logo → System Settings .
- Wait for a few seconds until your Mac connects to your Wi-Fi.
Repeat the steps of renewing the DHCP lease on your Mac, and then try connecting to your network.
When you try to perform configuration changes to the system, your Mac’s firewall experiences configuration issues. Let’s fix this problem by resetting the Firewall.
8. Reset the Firewall on your Mac
- In the menu bar, click Go → Go to Folder .
- Restart your Mac.
After your system boots, it’ll ask you to allow access to numerous programs and services. You may choose to enable access depending upon your choice. Then, try connecting to your network and check if the self-assigned IP address error persists.
If you are unsure about deleting the Firewall files, you may temporarily disable it. Toggling off the Firewall on your Mac can help determine if it’s causing conflicts with network connectivity.
- Select Network from the left panel → Choose Firewall .
- Restart your Mac and turn it on again.
9. Set Service Order from Mac’s network settings
Adjusting the service order can prioritize the network interface, ensuring your Mac connects to your preferred network.
- Click the Apple logo → System Settings → Network .
10. Change DNS Servers on macOS
Discarding existing DNS and switching to alternative DNS servers can resolve DNS-related issues that may contribute to the self-assigned IP address error.
- Open System Settings → Wi-Fi → Click Details beside your Wi-Fi name.
- Add these numbers: 22.214.171.124 126.96.36.199 188.8.131.52 184.108.40.206
11. Check for conflicting IP address
Ensure that no other devices on your network use the same IP address as your Mac. Check your router’s DHCP client list and verify that all devices have unique IP addresses assigned.
12. Disable VPN
If you have a VPN service enabled, disable it temporarily to see if it resolves the self-assigned IP address error. Open your Mac’s VPN settings and turn off the VPN connection.
You may need to attempt more complex fixes if the troubleshooting techniques outlined above do not fix the self-assigned IP address problem on your Mac:
- Update your Mac to the latest OS version.
- Verify your Mac is not infected with any malware or viruses.
- Ensure your network devices are operating well and there are no hardware problems.
- Reset NVRAM or PRAM on Mac to clear up the system settings memory.
To use a static IP address, go to Apple logo → System Settings → Network → Wi-Fi → Details beside Wi-Fi name. Select TCP/IP → dropdown arrow next to Configure IPv4 . Choose Using DHCP with Manual Address and enter the static IP address. Click on OK to save.

How do I get rid of a self assigned IP address?
I've tried all the usual things like restarting the computer and modem. Other devices in the house are able to connect. Sitting side by side.
I've had this iMac for a number of years but never encountered this before. I found this blog about the issue but it did not work for me - https://www.igeeksblog.com/internet-not-working-due-to-self-assigned-ip-address-on-mac/
I did not have the 'com.apple.network.identification.plist' file so wasn't able to delete it. Seems like a number of others who didn't have the file couldn't fix the problem either.
What can I do? It's impossible to get any work done as this computer is my main one! I'm running Catalina 10.15.3
Hoping someone out there can help.

Hello I recently instakked BIG SUR on my late 2013 macbook pro and I am having trouble tethering my Iphone XR to it. I can tether using wifi, but when I attempt to tether using bluetooth, my phone shows as connected in bluetooth preferences on my macbook and iphone, with the connection/link symbol shown on my iphone, but the internet will not work. In Network the bluetooth Pan shows an orange dot, STATUS: CONNECTED, but underneath it says ‘internet-not-working-self-assigned-ip-address-issue’. Do you have any ideas on how to fix this, I followed your instructions from the link ( https://ioshacker.com/how-to/fix-internet-not-working-self-assigned-ip-address-issue ) on your website, but each time I restart the computer the files that I put into the trash and delete from the trash re-appear in the system configuration folder. Only 2 of the 3 files you suggested to trash are in the folder, – com.apple.network.identification.plist – is not in the folder. Any advice appreciated.
I’m running Monterrey on my MacBook Pro and was having problem with the self-assigned IP and cannot connect to the Internet. I followed what your article suggested, several times, but was still unable to resolve the problem. Are there other suggestions that you think I should try? Thank you.
I just had the same issue and none of the fixes found online worked. I have McAfee Security software installed and there was a service running called McAfeeSystemExtensions. I deactivated the service within the Network settings and problem resolved.
