There is not yet a consensus understanding of what the problems are;
that's a prerequisite to avoiding repeats.
IPv4 was patched (well enough) to handle all the problems it
encountered, until we hit address exhaustion.
Some of the next couple of decades' problems may require another new
protocol, hitting a non-address-exhaustion problem.
That new problem could come out of various topology changes, inherent
mobility, lots of other things. It could even come from address
management (we won't likely exhaust 128 bits, but could hit
configurations we can't route). Or from out of left field.
