So... how would a strict IPv4 router handle the case where 8.8.4.5.13.9/40
should be routed to Cogent, but 8.8.4.5.17.168/40 should be routed via
Hurricane Electric, and no you can't just route to wherever 8.8.4.5 goes
because there's yet another peering war and nobody's baked a cake yet, so
sending packets for either route to the wrong link will cause blackholing?
