That was the intention of the table. TC (TCPdpriv - described in detail in Appendix B.3) preserves both the format and the longest prefix match but uses a random replacement for the remainder of the address.

Alissa suggested moving the table to Appendix B so it is in the context of the more detailed definitions of the categories and the individual techniques. I think that is a good idea - do you think that would address your concern?
