IPv6

Situation: A small LAN comprising a Windows 7 Ultimate x54 PC, 2 XP Pro x86 PCs and an Asus router.The Win 7 box has IPv6 enabled. There are no other IPv6 enabled devices on the LAN.

In my firewall I see numerous requests originating from the Win 7 PC, which are for the Multicast address ff02::1:ff.... which is a Solicited-Node address query and has a scope of 2 which equates to the local link.

As far as I knew local link addresses are filtered by routers, hence local link. Given that situation I'm wondering why I'm seeing these queries being generated to various addresses?

Any ideas?

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? Should you even care if you’re using IPv6 yet? Switching from IPv4 to IPv6 will give the Internet a much larger pool… >>> More

When the server has the network interfaces idle with no traffic for about 10 minutes, then… >>> More
