A NAT rule takes 10 seconds to set up for any network administrator, and it just works.
What if your service provider doesn't give you an IPv4 address? Many service providers only give IPv6 addresses now and use DS-Lite or even nat64. In most cases you do not have the ability to map ports on IPv4. NAT is evil.
Moreover, for those who definitely do not like NAT, there are plenty of 44.x.y.z AMPR IPv4 adresses available to the HAM community.
Most hams cannot announce a subnet via BGP to their service provider. The IP-IP tunnel gateway all flows via one point in San Diego. It's useless for VoIP.
I'm working in IT services for small businesses. I do not use IPv6 at all.
You're doing a disservice for your customers if you do not enable v6 for them. IPv4 run out has made v4 expensive.
I absolutely do not need it, and most of our ISPs here do not provide IPv6 connectivity.
Your provider is deficient. Many are, and the only way to get it fixed is by demanding proper IPv6 deployment.
Moreover, setting up an IPv6 network, and a dual-stack IPv4/IPv6 network, creates far more problems than it solves. For example, I spent dozens of hours last month to track a bug in my firewall's provider firmware, where IPv6 rules conflicted with IPv4 ones.
IMHO, IPv6 is absolutely not a feature I would request and/or enjoy, at least for the next 10 years !
It's this Luddite attitude that has got us into the place we're at now in IPv6.
50% of traffic on mobile networks to the major content providers is now via v6.
