[Lista ArNOG] IPv6 en ISP

[DeLong, Owen]

Nibbles are four bits, so all of /48, /52, :56, /60, and /64 are nibble boundary. /63 is not a nibble boundary. /48, /56, and /64 are also octet boundaries.

I'm well aware of the arguments claiming /48 is too much, but in my opinion, that's IPv4 thinking applied to IPv6.

En algunas implementaciones de ISP utilizan esta opci?n de direccionamiento:

It is highly recommended to hand off a /48 to each customer as well.... (then  the customer router can do /64 via dhcp).
It has been argued widely that /48 is too much and a /56 may be adequate for a Resi User...
    (/48 per customer
    (/56 per customer site
    (/64 per link  )
It is widely frowned upon (for technical reasons) to hand off just a /64 to each customer.
With IPv6, one has to stop thinking in-terms of quantity of IP's, and pay more attention to the level of sub-neting (@ nibble boundaries) possible...
    * How many subnets do I give my customers?
                  - /64 (1 subnet)          << Nibble Boundary
                  - /60 (16 subnets)
                  - /56 (256 subnets)      << Nibble Boundary
                  - /52 (4096 subnets)
                  - /48 (65536 subnets)  << Nibble Boundary
