I strongly advise you to not assume that just because an IPv4 address
is "public" (which I'm reading as RFC1918) means that it's not NATed.

I learned the hard way that Tmobile, for one, squats on other
organization's public IP space on their mobile network and NATs it to
address space they are actually assigned.  What you really mean is if
your IPv4 is not NATed, then it should not "feel slow", the type of
address isn't necessarily an indicator.

If we're being pedantic, yes.
