We've also had IPv6 enabled on our wireless for many years. The TCAM usage on the 6k Sup2Ts hits about 50% utilization these days so we still have a comfortable margin. Even then there are the XL sups available with gigantic TCAMs. This is with ~2500 APs and tens of thousands of concurrent clients. The main issue we still have is Androids stubborn insistence on avoiding stateless autoconfig, so we have DHCPv6 running.
