alt Hacker NewsExactly. Spectrum delivers good IPv6 service in my area. I tried it when I upgraded my gateway. All of my devices are assigned 4 IPv6 IPs, hostnames are replaced by auto assigned stuff from the ISP, and lots of random things don’t work.
I went from being pumped to learn more to realizing I’m going to invest a lot of time and I could not identify and tangible benefit.

Loopback, link local and network assigned. What's that problem? Your ipv4 hosts are can reach themselves through millions of addresses already.

Hostnames replaced? IPv6 doesn't do DNS...

Lots of random things also don't work on ipv4. :)
The biggest tangible benefit is you don't need to worry about NAT port mapping any more. Every device can have a public address, and you can have multiple servers exposing services on the same port without a conflict.
(The flip side is having a network-level firewall is more important than ever.)
You also don't have to worry about running a DHCP server anymore, at least on small networks. The simplicity of SLAAC is a breath of fresh air, and removes DHCP as a single point of failure for a network.
