I must admit I'm at a loss about this IPv6 hate. I love IPv6.
I love that (almost) every IPv6 subnet is a /64. Just this morning I assumed an IPv4 subnet was a /24, only to discover it was a /20, causing me to spend a couple of minutes re-working.
I love that (almost) every IPv6 is a /64 because you'll never have to widen a subnet because you started of with a /24, but then after your office grew to 200 people you had to switch to a /20. And no matter how automated you are, there are always some important devices that have static IPs and that you have to reconfigure manually.
I love that every IPv6 client gets a routable IP. This means NAT isn't necessary. NAT is a clever hack, but we've grown so accustomed to it that we've become blind to its failings. I've had to trace packets coming out of a corporate NAT, then into an AWS ELB (Elastic Load Balancer) back into a different NAT. With the IP address remappings, it's awful
IPv4 NAT can also lead to IP address collisions. Your home subnet is 192.168.0.0/24? And so's your work? Good luck VPN'ing in.
I like that IPv6 has an abundance of IPv6 addresses—I don't need to share the ports on my sole IPv4 address to 5 different machines.
