This was my impression until recently too; I thought that, by default, 
AD members with "client" role had 6to4 disabled, with Teredo and ISATAP 

However, I've recently concluded this must be untrue or incomplete, 
based on observations at our site.

Can anyone state with confidence what the default behaviour matrix is?
