Dual stack hotspot/captive portal

Maybe I misunderstand your point, but how is that any different from today on a client attached to open service set and using a captive portal?

If you want last mile protection, nothing other than 802.1x or IPSEC tunnel to start encryption will do. And maybe Hotspot 2.0 will make that more palatable in the not too distant future. That is at least what you can probably expect from the carrier community on this point -- and another topic altogether that has nothing to do with IPv6.

Not protecting users from man-in-the-middle attacks and session hijackings is really bad business practice. You need to protect the users MORE in that kind of environment than on an enterprise LAN. The most adverse environment securitywise is the role of an ISP, not the enterprise. > To me, captive portals are just fine with router advertisements and I > don't see real need for DHCPv6.

You use RAs always, even in DHCPv6. You probably mean SLAAC. And I would design it so that people with DHCPv6 support get IPv6, if they don't, they don't get IPv6. No SLAAC allowed. I guess we can agree to disagree. -- Mikael Abrahamsson email: swmike at swm.pp.se
