What is it and does it belong on wife's PC?

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,

Note: I x'd out most of the addresses to keep within forum policy.

Yes, it's IPv6. Here are instructions to disable it if you wish:

I've read that Windows 7 only requires it if you use the "home group" feature.

 

Thank you Victek123. I will leave it alone. Thanks again for your reply. Just had a tsunami here but so far not too big. Have a good one.
