Sure, and if Curt had quoted two paragraphs about ULAs instead, I would have pointed out that the user-generated pseudorandom global ID within them means that they too are unlike local IPv4 addresses, ie not fundamentally identical. A consequence of IPv6 ULAs having a global ID is that it should be straightforward to merge a number of local sites with independently assigned addresses, without causing any collisions. Perhaps that clarifies what I took from Curt's use of the term "fundamentally identical" with respect to IPv4 local addresses. > Then the GUA prefix is being used to connect to other computers > on the internet outside your network.
