I’m not saying it’s not a potential concern, but between wider and wider use of NAT and IP exhaustion coming largely from mobile devices and IoT, there are ways to handle it without removing IPv4 from regular ISPs.

Home internet won’t lose IPv4 until it’s absolutely unavoidable, and FL’s gonna be long dead by then.

Yes, I have read about the same thing on a few websites.
To be honest, I think it is a shame that Microsoft never released the source code (they lost it ? Really?). All issues could have been avoided since a long time if they did.

Any way, all the best for 2018 to all FL fans !
