I believe it applies universally to all end sites, including residential customers. I’m running a /48 in my home. The question you are asking reflects a vision of the household as it is today. A relatively flat network with a few devices on it. The reality of tomorrow is going to be quite different. We don’t know exactly what it will be. By giving residential end-users /48s, we have very near zero risk of running out of IPv6 addresses (this has been rehashed many times in many fora) and yet we allow for quite a bit of latitude for innovation in home networking. In the future, lots of things that aren’t routers today will, in fact, likely be routers and they will likely create subnets behind them. This is one of the reasons to have DHCP-PD. > I'm sure this has been discussed to death here and elsewhere.

Do not make the mistake of engineering your IPv6 deployment to only meet your past or present needs, but instead design it to be flexible and ready to meet your future needs as well.
