A /48 is a much better choice than a /52. For most deployments it is plain not possible to reserve a /48 for "WiFi", if all they have is a /48 for a whole "site". Thinking we have arbitrary number of /64s to burn will have a hard landing when reality comes along. Gert Doering -- NetMaster --=20 have you enabled IPv6 on something today...?
