Services Utility: IPv6 Helper Service Service | Display Name (?): | IPv6 Helper Service | | Short Name (?): | 6to4 | | Executable (?): | svchost.exe | | Library (?): | 6to4svc.dll | | Depends On (?): | Remote Procedure Call (RPC), Windows Management Instrumentation | | Supports (?): | None. | | Description (?): | Provides DDNS name registration and automatic IPv6 connectivity over an IPv4 network. If this service is stopped, other computers may not be able to reach it by name and the machine will only have IPv6 connectivity if it is connected to a native IPv6 network. If this service is disabled, any other services that explicitly depend on this service will fail to start. | | OS (?): | XP Home/Professional, Vista Home/Business, Server 2003, Vista Server | | Startup (?): | | Default | Home | Workstation | Server | Minimal | Tweaked | Automatic | | Automatic | Disabled | Automatic | Automatic | Disabled | Disabled | Disabled | |
Explanation (?): |
This service allows the ability to tunnel TCP/IP version 6 network communications through a TCP/IP version 4 network. Also known as IPv6 this technology provides a greater range of IP addresses and other abilities such as quality of service (QoS) are natively supported. This service is really only useful for computers that are transitioning to IPv6 through the use of 6to4 (see RFC 3056). At this point IPv6 is supported in a great deal of the Internet's infrastructure, but it is many years away from being used exclusively. You can safely disable this service if you don't require IPv6 network communications, but I'd suggest that you remove it instead. You can remove this service by removing the network protocol called "Microsoft TCP/IP version 6" from the Windows network properties. |
