Of course I configured the Airport Extreme with a name, management password, and confirmed IPv6 was set to to configure Automatically and Native.

My testing on OS X Mavericks shows that an Airport5,117 with firmware 7.6.4 creates the guest wireless network:

1. With an IPv4 address from an automatically assigned RFC1918 LAN connected through NAT to WAN.

2. With NO IPv6 addressing of any kind.

My conclusion is that Apple does not yet support IPv6 in any fashion for Wireless Guest networks.
