ipv4 routing defragment and not hierarchical

Hello experts,

I read some articles and it said that ipv4 is not efficient as it is not design with the hierarchical structure in place (like ipv6) and the routes are fragmented. That is the reason why we have so many routes in the routing table on the Internet routers.
I will really appreciate if you can elaborate on that. Thanks

Effectively NAT only added about 10 or 12 bits at best to available addressing with a LOT of hindrance.
Ever looked into SIP protocol packets, they are a nightmare now.
just to support crossing borders. Including extra protocols to just find out the external address, which comes in several variaties because some router manufacturers when into the 2nd guessing game on it...
