I have most of my PC & notebook stuff on IPv4 only, and I have my home router on IPv4 only, and I have never met any connectivity issue so far, that I couldn't reach a service. But I had several severe network connectivity issues in the not-so-distant-past with machines that had IPv6 enabled, and those problems vanished completely when I disabled IPv6 on the machine. No end-user needs IPv6, really. -Martin
