Right and wrong in this context is subjective there are many things in IPv6 that I find to be wrong convoluted and overly complex

When IPv6 was created they had the opportunity to just make it an expansion of the IPv4 space they chose not to do that and instead they added in a bunch of wish list items that were not needed to accomplish the goal that they were seeking to do which was prevent the exhaustion of IPv4 addresses

Absent address space exhaustion I massively prefer working with IPv4 than I do IPv6
