Double Local Link (Scope:Link) IPv6 address on one interface
 

Hello. I configured the IPv6 on this CentOS interface.
im using the local link addr. (fe80::xxx). everything is good.

Done all, i restart the network, and suddenly an extra local link inet6 appeared suddenly

inet6 fe80:xxxxx:2855 Scope:Link
inet6 fe80:xxxx:8411 Scope:Link


i configured the .285 ipv6 address, using

nano /etc/sysconfig/network-scripts/ifcfg-eth0

but why suddenly an extra .8411 address appeared?
that address was not inside /etc/sysconfig/network-scripts/ifcfg-eth0.

really blur, why i have an extra address there?
