[SOLVED] Asus RT-N56U & Realtek's integraded NIC
« on: June 13, 2014, 08:38:01 AM »

Hi,

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

Code: [Select]
eth0      Link encap:Ethernet  HWaddr 00:19:66:xx:xx:6d
          inet addr:192.168.1.186  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::219:66ff:fede:3a6d/64 Scope:Link
          inet6 addr: 2001:470:xx:xx:4562:4a08:bc9d:a1f4/64 Scope:Global
          inet6 addr: 2001:470:xx:xx:219:66ff:fede:3a6d/64 Scope:Global
          inet6 addr: 2001:470:xx:xx:b50c:6bbb:6b3f:db4e/64 Scope:Global
          inet6 addr: 2001:470:xx:xx:4cd8:404f:79a9:bd73/64 Scope:Global
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:605802 errors:0 dropped:0 overruns:0 frame:0
          TX packets:452614 errors:0 dropped:235 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:405305447 (405.3 MB)  TX bytes:164951411 (164.9 MB)

Router IPV6 tunnel interface:
Code: [Select]
v6in4      Link encap:IPv6-in-IPv4
           inet6 addr: 2001:470:27:a4::2/64 Scope:Global
           inet6 addr: fe80::50de:eec1/128 Scope:Link
           UP POINTOPOINT RUNNING NOARP  MTU:1480  Metric:1
           RX packets:551969 errors:0 dropped:0 overruns:0 frame:0
           TX packets:294701 errors:0 dropped:0 overruns:0 carrier:0
           collisions:0 txqueuelen:0
           RX bytes:598239096 (570.5 MiB)  TX bytes:47208342 (45.0 MiB)

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:

The only things that can assign IPv6 are..

RA (SLACC)
DHCP6v
Manual

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