Using the firewall contained in Trend Micro Internet Security, all household computers show an IP address of 192.168.xxx.xxx. But my wife's computer shows an extra connection of fe80::47d:1f3f:xxxx:xxxx. I'm pretty sure it's an IPv6 connection but is it necessary and do other computers have a similar IPv6 connection? She runs Windows 7 Professional 64 bit. Thanks for any replies, SourMilk out Note: I x'd out most of the addresses to keep within forum policy.
