Description (last modified by joelja@…)


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

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

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? :)

This looks like a dup of #29 - did my blacklist entry from yesterday expire?

I noticed this RA again, from the same IP address and same MAC address, so I blacklisted it again in the Aruba - 00:19:d2:7f:a6:52 .

Obviously, "blacklist" does not mean what I think it means, since this is back again.
