How to Disable Ipv6 on Mac?

Have you been wondering how to disable IPv6 on your Mac? You’re not alone. While IPv6 was designed to replace IPv4 and provide more IP addresses, many people find it can cause connectivity or other unintended network problems. If you’ve tried various network troubleshooting steps but still suspect IPv6 might be the culprit, disabling it on your Mac is worth a shot.

The good news is, it’s a straightforward process that only takes a few minutes. In this article, we’ll walk you through how to turn off IPv6 on your Mac. By the end, your Mac will be using the IPv4 protocol exclusively and your network issues will be a thing of the past.

Why Would You Want to Disable IPv6 on Mac?

There are a few reasons this can come in handy:

  • IPv6 is the newest version of the Internet Protocol, but only some networks and devices support it. Disabling IPv6 ensures you’re using the IPv4 protocol that almost everything understands.
  • Certain apps or network equipment may not play nicely with IPv6 enabled. If you’re having connectivity issues, disabling IPv6 is an easy thing to try.
  • IPv6 can pose some security risks if not properly configured. Disabling it eliminates that concern altogether.
  • You can optimize your network performance. Since not everything utilizes IPv6 yet, disabling it can prevent potential slowdowns from IPv6 traffic.

How to disable IPv6 in macOS Big Sur Windows?

To disable IPv6 on Mac running macOS Big Sur, you must make a few changes in your Network settings. IPv6 is the next-generation Internet protocol, but some networks and devices still use the older IPv4 protocol. Disabling IPv6 ensures full compatibility.

Open your Network Preferences

Go to the Apple menu > System Preferences and click “Network”. This will open the Network preferences pane where you can view and edit your network settings.

Select your Network Interface

On the left side, select either Wi-Fi, Ethernet or Thunderbolt Ethernet, depending on how your Mac is connected to the network. The options for that network interface will appear on the right side.

Click “Advanced…”

At the bottom of the network interface window, click the “Advanced…” button. This will open advanced options for your network connection.

Uncheck “Enable IPv6”

In the Advanced Network settings, uncheck the box next to “Enable IPv6”. This will disable IPv6 for the selected network interface.

Repeat for Other Network Interfaces

If your Mac uses multiple network interfaces, like Wi-Fi and Ethernet, repeat the steps to disable IPv6 on each interface. This ensures IPv6 is disabled system-wide on your Mac.

networksetup -setv6off Wi-Fi

networksetup -setv6off Ethernet

Check your IPv6 Status

To confirm IPv6 is disabled, open the Terminal app on your Mac and run the command: networksetup -getinfo “Wi-Fi”. Replace “Wi-Fi” with your network interface name. The command should return “IPv6: Off”. If it says “On”, IPv6 is still enabled for that network interface. Repeat the steps to disable it.

Check your IPv6 Status

Disabling IPv6 may solve network connectivity or compatibility issues with some networks and devices. If you continue to have problems, contact your network administrator or internet service provider for further help. You can also check for IPV6 leakage by performing IPV6 leak test.

Q: Do IPV6 uses Mac?

Yes, Mac operating systems support IPv6. In fact, IPv6 is enabled by default on Mac. This means your Mac can connect to networks and websites using either IPv4 or IPv6.

Q: Does enabling IPv6 can disable IPv4?

Enabling IPv6 on your Mac will not disable IPv4. Mac supports both IPv4 and IPv6, and will use whichever version is supported by your network and the websites you connect to. Most networks and websites still use IPv4, so your Mac will typically connect using IPv4. However, enabling IPv6 provides additional connectivity options for newer networks and services.

Q: Is MAC address same as IPv6?

No, a MAC address and an IPv6 address are not the same. A MAC address is a unique identifier, like your Wi-Fi adapter, assigned to a network interface. An IPv6 address is an Internet Protocol address used to identify your device on an IPv6 network. While a device will have the same MAC address no matter what network it joins, its IPv6 address will change based on the network.


While IPv6 is the latest internet protocol and provides some benefits over the older IPv4, it can sometimes cause issues with certain networks and devices. Disabling IPv6 is an easy fix if you’re experiencing connectivity or performance problems. Now you can get back to surfing the web, stream your favorite shows, and do whatever you love online without worries. If you do run into any other network hiccups in the future, you know where to find helpful tips and tricks.
