That was some tunneling mechanisms, Jordi can explore more. I would just remove that section, but Jordi wants to elaborate on this ;) > 3.2.2: /48 for all is most practical & most pragmatic?

Why not ;) If you burn your IPv6 space, you get new allocation. This should not be a problem, specially because RIPE NCC default mathematics is based on /48-per-customer, at least that's what I remember. > 4.2. even though I generally agree that dynamic assignments have more > disadvantages (than benefits), the need to have a logging system is > usually not one of them, as most (if not all) ISPs have that covered > long before IPv6 (e.g. RADIUS accounting) ack. > > As more general final comment, I believe that such a document would > definitely benefit operators just starting out Thnx!!!
