Most of us use ::1 for the assigning side and ::2 for the non-assigning side of
the connection. On multipoints, such as exchanges, the popular alternative is
to use either the BCD of the ASN or the hex of the ASN for your first connection
and something like ::1:AS:N for subsequent connections.
If you have shared racks with different customers within, you can use 16
or 32 bits out of 64 as customer ID, allowing the customer to use the
rest, so in fact giving him trillions (possible) IP's for one server.
It can be use with autoconfiguration which always has FF:FE in the
middle - you just use some other bits here for your customer
assignments. Thus you identify a customer just by looking at the IP address.
