IPv6 is the next version of the IPv4 Internet Protocol and was created to simplify the configuration and management of IP networks. Compared to the previous protocol, IPv6 allows for a much larger number of IP addresses, but at the same time causes problems on Active Directory and on shares.
In most cases, the activation of the IPv6 protocol in home networks is useless, as well as harmful, as it sometimes leads to connection difficulties and blocks on shares with other devices. There may also be problems leak using a VPN connection (so it’s always useful to know which VPNs support IPv6).
The simplest and most immediate solution to solve these problems is disable IPv6. In our new in-depth study we will explain how to disable it on Windows 11, Windows 10 and Mac.
How to disable IPv6 on Windows 11
The step-by-step procedure for disable IPv6 on Windows 11:
How to disable IPv6 on Windows 10
Here are the steps to follow for disable IPv6 on Windows 10:
How to disable IPv6 on macOS
Instead, these are the instructions for disable IPv6 on macOS:
Theoretically there is also another proceduremore immediate than the one just described, but several models do not support it.
This procedure consists in accessing the card “Net” from “System Preferences”select the WiFi network to which you are connected, then click on the “Advanced” button and, in the new screen that appears, select the option “No” from the drop-down menu next to “IPv6 Configuration”. As mentioned, not all Macs support this feature: you know if instead of “No” the item appears “Local link only”.
This is why the first procedure, although it is a bit more difficult due to the code to be typed, is still the best solution today to disable the IPv6 protocol on WiFi and Ethernet.
