[SOLVED] Asus RT-N56U & Realtek's integraded NIC

[samip]

Hi,

I'm confused why does my computer have this many IPV6 addresses assigned?

Take with gain of salt, as I am a bit tired, but,
I think the answer to your question is ipv6 privacy extension.

Some reading you can do about it:
http://tools.ietf.org/html/rfc4941
https://home.regit.org/2011/04/ipv6-privacy/

The only things that can assign IPv6 are..

RA (SLACC)
DHCP6v
Manual

He's right in that the culprit is probably privacy extensions.
