Hi,

We still have a rogue RA on the wireless network today, the same one as
yesterday.

The Ethernet source of the RA is an Intel adapter 00:19:d2:7f:a6:52.

The IPv6 source is fe80::6c4e:8ed1:3ad2:4cc4 which might be a Windows
Vista 'randomised' host address.

It's advertising prefix 2002:8281:1394:9:: so has IPv4 addr 130.129.19.148.

It's also offering an fec0:: prefix so is probably running Windows ICS
(perhaps because the system has IPv6 on but is filtering incoming IPv6 RAs
 in the host firewall?)

Anyone got any other clues?

Anything the local ops guys can do? :)

Tim
