IPv6

For some reason I'm receiving numerous alerts, for a variety of processes, from my firewall. These are all related to ICMPv6 and are the same, apart from the process for which the alert was generated.

'Application/Process' Is trying to Access the Internet Remote Address - fe80::7191:6bd1:e5fa:58af [The Link Local Address] ICMP Type = 1 [Destination Unreachable] ICMP Code = 3 [Address Unreachable] Protocol = ICMPv6

Allow or Block

If I Allow or Block, the alert never reoccurs. I understand what the various elements of these messages represent, I just can't fathom out why they are being generated.

What could be the reason for these Alerts?

OS - Windows 7 x86 Ultimate

Thanks

IPv6 is extremely important for the long-term health of the Internet. But is your Internet service provider providing IPv6 connectivity yet? Does your home network support it?
