If you’re arguing that only public attachment points to the Internet need IPv4 addresses, you’ll get little argument from me, although those who are involved with actual critical infrastructure may have a different opinion. However, my impression was that people were throwing more into the “Critical Internet Infrastructure” bucket, e.g., ARIN and ICANN/PTI. My question was really the part that you removed: "The definition of “CII” used here appears to be arbitrary. Perhaps it might help if you define what you think is CII and why ARIN and ICANN/PTI would fall under that definition whereas Verisign wouldn’t?" Regards, -drc
