Question: what is the difference between ipv4 vs. ipv6 routing?
Answer: On the surface, it might seem that the IPv6 address format has a higher complexity and could clog things up from a routing perspective, but the subgroups of IPv6 actually enable faster delivery. IPv6 generates a 128-bit address, while IPv4 creates 32-bit addresses, so there will be room to grow with the new system.
