ARCHIVED: What is IPv6, and how do I disable it?

IPv4 is the current Internet protocol; however, because the number of available IP addresses is diminishing, IPv6 will eventually become the standard protocol. IPv6 increases the number of IP addresses available and improves IPv4's routing and network auto-configuration abilities. For more, see Microsoft's IPv6 and IPv6 networking at IU.

If you want to disable IPv6 (e.g., for troubleshooting), see the appropriate instructions for your operating system:
