Prefer IPv4 over IPv6 | Dec 32 Hex 0x20Bin xx1x xxxx | Recommended instead of disabling it. |
Disable IPv6 | Dec 255 Hex 0xFFBin 1111 1111 | See startup delay occurs after you disable IPv6 in Windows if you encounter startup delay after you disable IPv6 in Windows 7 SP1 or Windows Server 2008 R2 SP1. Additionally, system startup will be delayed for 5 seconds if IPv6 is disabled by incorrectly, setting the Disabled Components registry setting to a value of 0xfffffff. The correct value should be 0xff. For more information, see Internet Protocol Version 6 (IPv6) Overview. The Disabled Components registry value does not affect the state of the check box. Therefore, even if the Disabled Components registry key is set to disable IPv6, the check box in the Networking tab for each interface can still be checked. This is expected behavior. |
