>…too lazy… I thought this too, until I tried to add IPV6 support for a fairly simple web application. The single biggest problem is the quality and consistency of IPV6 implementations is frequently very poor. I ran into many bugs, strange inconsistencies and poor handling of edge cases by middleware, clients, routers and firewalls that any advantage from IPV6 was simply not worth it for our needs. Mobile telcos and cloud providers are currently the only parties where the benefits of V6 outweighs the pain, and as such their software and services tend to support it quite well. While the cost of V4 is going up, for almost everyone it’s still far less than dealing with V6, and there’s nothing relevant (unless you have telco/cloud provider needs) V6 can provide you that V4 can’t.
