Looks like another Thinkpad machine because the OUI for this new
mac-addr matches the OUI of the previous machine sending Rogue RA.

Dear All,

"00:21:6b:3c:8c:e2" has been blocked from IETF76 WiFi at 2:00pm.

Please, people who owns this client contact to the Helpdesk in 
the terminal room or NOC in the UME(4th Floor).
(See the IETF message board)

Also, we are hunting another Rouge RA client on the venue.
MAC address is "00:1b:77:bc:a4:e6" in the ORCHID West.
If RA sending from this client will be continued, we will block 
the client.

Regards,
