I mentioned that we often get rogue RAs on wireless networks. Conferences are no exception. As of right now on my laptop (in the : michael@eth-0-1e-c2-bf-f8-82:~$ ifconfig en1 en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 192.35.167.8 netmask 0xfffffc00 broadcast 192.35.167.255 inet6 fe80::21e:c2ff:febf:f882%en1 prefixlen 64 scopeid 0x6 inet6 2620::ce0:1:21e:c2ff:febf:f882 prefixlen 64 autoconf

Fortunately, my default route hasn't (yet) changed so I am not having any connectivity problems related to this. If I have decoded the 6to4 address properly, the RAs are being announced by the host with IPv4 address 75.196.207.17, which is a Verizon Wireless data IP address. If this is you, can you please turn off connection sharing while you're in the conference area? Also, I wouldn't mind learning more about your configuration (if you're willing to chat) so that I can replicate it in the lab. I am testing various defenses against rogue RAs. thanks, michael
