10. IPv6 Addressing Structure
Site prefix, 48 bits, describes
the public topology; allocated to
your site by an ISP or RIR.
16 bits, describes the describes
the private/site topology;
allocated by site admin.
also referred to as a token; either
automatically configured from the
interface's MAC address or manually
configured in EUI-64 format.
nibble
32 hex

11. Abbreviating IPv6 Addresses
2001:0000:3238:DFE1:0063:0000:0000:FEFB
1. Discard leading zeros:
2001:0000:3238:DFE1:63:0000:0000:FEFB
2. Shrink down to a single zero.
2001:0:3238:DFE1:63:0:0:FEFB
3. Successive fields of zeros can be represented as :: only once per address.
2001:0:3238:DFE1:63::FEFB
