I have seen some that don't. Back in early days of residential ISPs to offer IPv6. But, that's a thing of the past - and the same mistakes happened on the early IPv4 routers when dialup was disappearing, and DSL/Cable was kicking off.

Having IPv6 will be exactly as secure as IPv4+NAT by default on any CPE. And, just as with NAT+v4, it's possible to open your machines to the world if you have no idea what you're doing.

(This is actually pretty common for gamers who set the "DMZ host" router feature to aim at their desktop and flick off the firewall!)
