On Windows 11, the system uses both Internet Protocol version 6 (IPv6) and version 4 (IPv4) by default in a dual-stack configuration. While IPv4 remains the dominant protocol for most local networks, enabling both versions is highly recommended, as many modern applications now rely on IPv6.
However, if IPv6 causes connectivity issues or your network setup doesn't require it, Windows 11 offers several methods to disable the protocol through the Settings app, Command Prompt, and PowerShell.
