Consider that NAT64 is able to translate between IPv4 and IPv6 at the packet level. If the protocols were as different as you suggest, this wouldn't be possible.
- michaelt 3y agoDoesn't IPv6 remove broadcast, thus removing DHCP and ARP? I mean, hosts need to be 'dual stack' to support IPv4 and IPv6 together - whereas TheLoafOfBread's proposal would allow support of both with one backward-compatible stack.
- p1mrx 3y agoDHCP and ARP use 32-bit addresses, so those protocols had to change regardless. I would challenge you to find someone who knows the difference between Ethernet broadcast and multicast without looking up the answer. They are very similar mechanisms.
- yencabulator 3y agoNAT64 is never in a position to need to translate DHCP & ARP, those live fully on one side of NAT64 ("4" side for DHCP & ARP, "6" side for SLAAC/DHCPv6 & NDP). NAT64 is involved on the level of TCP & UDP, not lower level protocols.
