As long as we are talking about ARP, I want to mention that IPv6 does not
use ARP. Instead, it uses NDP (neighbor discovery protocol) with some
ICMPv6 multicast messages, and the "modern" iproute2 tool which works
across ipv4 and ipv6 is "ip n", where n stands for "neighbour".

Obviously, much additional reading is available, almost certainly more
accurate than my cartoon version here.
