If you searched for ‘how to change your ip on mac’, this guide shows how to change your ip on mac using System Settings and a manual IP configuration on your own computer. It focuses on the local network address your Mac uses on your own home or office network, which is different from the public address the wider internet sees. Changing the local address is a routine network task: it can resolve an address conflict, help you test a device on a particular part of your network, or let you match a setup required by your own router. Everything here applies to your own Mac and your own network only, and you should not attempt to change the address of a device that does not belong to you.
Before you start, it helps to understand the two kinds of address involved. Your Mac usually receives a private local address automatically from your router, such as an address in a familiar home range. That address lets devices on your own network find each other. Your router, in turn, has a public address assigned by your internet provider, which is what websites see. The steps in this guide change the local address on your Mac. They do not change your public address on their own, and they do not hide your identity online. If you need to change a public address, that is a separate question involving your router or your provider, and it is covered briefly at the end of this guide.
How to Change Your IP on Mac in System Settings
The simplest way to learn how to change your ip on mac is through System Settings, the modern replacement for the older System Preferences panel. Open System Settings from the Apple menu, then choose Network in the sidebar. You will see your network services, such as Wi-Fi and Ethernet. Select the service you are currently using, then look for its details or advanced options. The exact layout varies slightly between macOS versions, but the principle is the same: find the TCP/IP section, where your Mac shows how it obtains its address.
In most home setups, the “Configure IPv4” option is set to “Using DHCP”. DHCP is the automatic system by which your router hands out addresses. To set an address by hand, change that option to “Manually” or “Manual”, depending on your macOS version. You will then be able to type an IPv4 address, a subnet mask, and a router address. The router address is the address of your own router on your local network, and the subnet mask is usually a standard value for a home network. Only choose an address that belongs to your own network range and is not already in use by another device, or you will create a conflict that takes both devices offline.
A safe way to pick an address is to look at the address your Mac already has, and change only the final number to a high, unused value within the same range, while keeping the first three numbers the same. For example, if your current address follows a common home pattern, you might pick a final number that is well above the range your router hands out automatically, which reduces the chance of a clash. After you type the new details, apply or save the change, then check that your Mac reconnects. Open a browser and load a familiar page on your own network, or check the Network panel again to confirm the new address is shown.
How to Change Your IP on Mac With a Manual Address
Learning how to change your ip on mac with a manual address is useful when you want a stable address for a particular purpose on your own network. A manual, or static, local address stays the same across restarts, which can help when you are testing a printer, a media device, or a development setup that expects your Mac at a known address. It is also useful when your router’s automatic range is crowded and you want to reserve a quiet corner of the range for your own machine.
To do this well, gather three pieces of information from your current connection before you change anything: your present local address, your subnet mask, and your router address. Write them down. Then, when you switch to manual configuration, enter the router address and subnet mask exactly as they were, and enter your chosen new local address. If you also need to enter DNS servers, you can use the DNS addresses your router already provides, which are normally shown in the same Network panel. Changing DNS is optional for a simple address change, and leaving the existing DNS settings in place is the safest choice for most people.
After applying the change, test the connection in two stages. First, confirm that the Mac itself reports the new address in System Settings. Second, confirm that the wider network still works by loading a website and, if you use shared devices, by reaching a local device such as a printer. If either test fails, return to the TCP/IP panel and switch back to automatic DHCP, which will restore a working address from your router. That fallback is your safety net, and it is worth remembering before you experiment: automatic mode will almost always get you back online.
Before you finish, double-check the steps for how to change your ip on mac against the address your Mac now reports. A guide to how to change your ip on mac is only useful if the finished setting matches a free address on your own network, so verify the result rather than assuming the change worked.
Avoiding Address Conflicts on Your Own Network
An address conflict happens when two devices on the same network try to use the same local address. The symptoms are familiar: one or both devices lose connectivity, web pages stall, and the network panel may warn about another device using the same address. Conflicts are easy to cause when addresses are set by hand without checking what is already in use, and they are easy to fix by returning one device to automatic mode or by choosing a different manual address.
Prevention is straightforward. Before choosing a manual address, check your router’s administration page for a list of connected devices, if your router offers one, and avoid every address on that list. Alternatively, choose an address near the top of your network range, well away from the pool your router hands out automatically. Many routers hand out addresses from a low part of the range, so a high final number is often free. If your router supports address reservation, that is an even better option: you tell the router to always give your Mac the same address automatically, which gives you stability without the risks of a fully manual setup.
It is also good practice to keep a short note of any manual addresses you set on your own network. A simple list, kept with your other household or office network notes, prevents future confusion when a new device is added or when someone else needs to troubleshoot the network. Note the device name, the manual address, and the date you set it. That small habit saves a surprising amount of time, especially in a home with many phones, computers, printers, and smart devices.
It also helps to practise reversing the change, because knowing how to change your ip on mac includes knowing how to undo it. Switch back to automatic DHCP once, confirm connectivity, and you will have proved that how to change your ip on mac is a reversible skill, not a one-way step.
When Automatic DHCP Is the Better Choice
Manual addresses are a tool, not a default. For most everyday Mac use, automatic DHCP is simpler, safer, and less likely to break when you move between networks. When you take a laptop from home to an office, a café, or a friend’s house, automatic mode lets it pick up a correct address for each new network without any changes from you. A manual address tied to your home network will usually fail on a different network, because the range, router, and subnet will be different.
Use a manual address only when you have a specific reason on your own network, such as a stable address for testing or for a device that expects one. For general browsing, email, streaming, and work, automatic mode is the right choice. If you set a manual address for a test and then forget about it, you may later wonder why your Mac struggles on a new network. That is a common cause of “Wi-Fi connected but no internet” complaints on laptops that travel.
The practical rule is therefore simple: set a manual address deliberately, test it, note it down, and revert to automatic mode when the need ends. If you are unsure whether you need a manual address at all, you probably do not. Automatic mode, combined with a router reservation where stability matters, gives you almost all of the benefit with far less risk of a conflict or a stale setting following your Mac to another network.
| Method | Best for | Watch out for |
|---|---|---|
| Automatic DHCP in System Settings | Everyday use and laptops that travel | Address may change after a restart |
| Manual address in System Settings | A stable local address for testing | Address conflicts if the address is already in use |
| Router address reservation | Stability without manual settings on the Mac | Requires access to your own router settings |
| Restarting the network service | Clearing a temporary glitch | Does not fix a wrong manual address |
One more practical tip for how to change your ip on mac: take a screenshot or a note of the original automatic settings before you switch to manual. That record makes how to change your ip on mac back to automatic a one-minute job, even months later.
Frequently Asked Questions About Changing Your IP on Mac
Will changing my local IP change what websites see?
No. The steps for how to change your ip on mac in System Settings change your local network address. Websites see your public address, which comes from your router and provider. Changing a local address does not anonymise your browsing.
What if I lose internet after a manual change?
Return to the TCP/IP panel and switch back to automatic DHCP, then apply the change. Your router should hand your Mac a working address again. If problems persist, restart your Mac and your router, in that order, and check again.
Do I need a manual address for everyday use?
Usually not. Automatic mode suits browsing, email, and work, and a router reservation is a safer way to get a stable address when stability matters on your own network.
Can I change someone else’s IP address?
No. This guide covers your own Mac on your own network only. You should not attempt to change, probe, or interfere with the address of a device that does not belong to you.

Conclusion
Knowing how to change your ip on mac through System Settings gives you a useful, controlled way to manage your own local network address. Choose a free address in your own range, keep the router and subnet details exactly as they were, test the connection, and keep automatic DHCP as your fallback. For most people, automatic mode remains the everyday default, with a manual address reserved for specific testing or stability needs on a network they own and control.
