Re: Dual stack IPv6 for IPv4 depletion

My parents are non-technical.

Other than a little help connecting her airport to the cable modem, I had nothing to do with the design and 
implementation of their networks.

They have at least 7 distinct subnets in their house that I know of.

Some of them are routed together. Some of them are isolated. I suspect my parents don’t even realize what a subnet is 
or how a router connects them.

It is unlikely, IMHO, that said topology will likely get flattened in the future. I expect, rather, that it will grow 
both vertical and horizontal.

I think that’s about as common person as it gets.

So I’m not talking about the 15-30 subnets in my house, depending on the day, nor the subnets outside of my house used 
to support the networking
in my house (point to point circuits and the like).

I’m well aware that the common person does not have an ASN for their home and the average home thinks BGP is probably 
an airport code.

I think you're confusing very common for a tech guy and very common for the common man. I have a dozen or two v4 
subnets in my house. Then again, I also run my ISP out of my house, so I have a ton of stuff going on. I can't even 
think of a handful of other people that would have more than one.

Talking about IPv6, we aren't carving a limit in granite. 99.99999% of home 
networks currently have no need for multiple networks, and thus, don't ask for 
anything more; they get a single /64 prefix. 

Personal-area networks already exist. Phone/watch/laptop etc. 

Virtual machines are common, e.g. for running multiple different operating 
systems on your computer. 

And automotive networks need connectivity. 

There are often separate VLANs for VOIP and IP TV and smart meters. 

Separate wifi networks tuned for low-latency synchronized audio. 

So it's very common to have multiple networks in a home with multiple 
layers of routing.
