If you have a router and ISP that give you an IPv6 address, then I suppose
IPv4 is not strictly necessary. However I would have thought that any
default installation of Windows, Linux etc would enable IPv4 by default, so
it would require explicit action to turn it off.

The whole concept of IPv6 fills me with horror. The idea that all LAN
devices have public IP addresses, and that all devices must have a good
firewall, instead of using the NAT and the firewall in the router, seems a
*huge* retrograde step in terms of security. By all means use IPv6 for the
router's public WAN address, to allow many more such WAN addresses in the
world, but I'd have preferred IPv6 to still use IPv4 addressing within the
LAN, and NAT to translate between WAN and LAN.

But they didn't do it that way (why?) so we've got to live with the
consequences of the way they designed IPv6.
