Subject: Re: Q: is RFC3531 still applicable?

Content-Type: text/plain; charset="utf-8"I never could understand the motivation behind RFC3531. Just assign
/64s. A single /64 subnet has 18,446,744,073,709,551,616 host
addresses. It is enough. Period.
With IPv6 when you think of assignment to end-user, it's better to think in terms of 'use case' rather than number of hosts within a single network.
As a residential user I might have wifi, voip, TV, CCTV,... each of them can use its own prefix.
As a bare metal user in a datacenter , I might have different needs when I build any internal networks.
As a corporate user, I think this one is the more obvious.
The only end-user who might stick with a single /64 is
- 1 smartphone
- 1 VM
