RFC1918 risk of collision is the reason to argue for IPv6 in the first
place. I work for one company that decided that squatting on 2.0.0.0/8
for their chassis communications was better than conflicting with RFC1918.
But, I didn't say it was risk of collision with ULA-R that was the
main problem, it is lack of reverse DNS and lack of whois that is the
problem.
