I really don't see why people think it's so different that v4. To me
back then it mostly seemed like v4 with bigger address. ND was just
ARPv2 and SLAAC was an alternative to bootp. DHCP didn't exist, nor
IPsec, nor NAT. What else does an ipv6 host need to implement?
My theory is that the real problem is that hardware switching arrived
before v6 and vendors didn't want to implement it because of cost. That
gave a great excuse for why providers couldn't deploy v6 which they
didn't want to do anyway.
