> Why would you make everything gratuitously complicated by having two separate forms of addressing? If it ain't broke, don't fix it? If IPv6 brings no benefit to my LAN, why should I spend all the effort needed to shift it to IPv6? I can just make the connection to the internet IPv6 and leave everything else alone. Although I have additional friction in my case, in that I have numerous devices that are IPv4-only. So…
Because that's not the way TCP was designed in the first place. Instead you're used to hack on top of hack to make IPv4 not explode in a ball of flame there are far more billions of end points than IP addresses. The thing is you really don't realize how shit your network experiences are because of this. Everyone is just attempting to tunnel more services via HTTP/HTTPS and the particular fun problems that entails rat…
But in my LAN, there is no IP address exhaustion. I have orders of magnitude more IP addresses than I'll ever use. IP address exhaustion applies to the internet at large. I'm not talking about that.
In the internet at large, IPv6 has to happen. In my LAN, I don't see a need for it. I can route between the IPv4 endpoints in my LAN and the IPv6 endpoints on the internet.
And because I have IPv4-only hardware on my LAN, I need an IPv4 segment to support it at the very least. So why not keep the entire LAN IPv4?
