(a bit dated, but shows the historic allocations)

Look up "CIDR", history thereof, for reasons why it looks this way.

Crazy how wasteful it is. I wonder what genius thought to allocate /8 to every company/organization. You don't need to have PhD in statistics and math to know there's more than 250 companies.
I wonder who will think about the genius who disbanded the EPA, rolled back every environmental protection there is and withdrew from the Paris Agreement at the most critical time for our planet in 40 years.

Hindsight is 20/20 and the „Internet“ was a mainly US centered university research project that was thought of as a toy by the far majority.

Everybody thought they‘d have a replacement for the initial assignment once things got serious... for more fun, google ipv6 history ^^

Wouldn't the more apt comparison be to the folks who set up the EPA in the first place (Nixon administration I believe)?
Maybe take a dose of humility and realize that at one point the fastest processors and memory systems in the world weren't capable of holding more than a limited size routing table, while maintaining acceptable line speed?

And that in the interests of working within the physical hardware limitations of the day, very smart engineers made the best choices they could?

Jesus.

What this has to do with anything? I'm saying that giving whole /8 (or I should say class A) to a company is wasteful. And you can only do it no more than a bit over 200 times. You are on the other hand saying that the hardware at the time wouldn't be able to handle all the companies. Why not allocate C blocks, or at very least B blocks? Or are you saying that they doubted hardware of the future would be capable of handling it?

Because of such wasteful allocation we got this "wonderful" thing called NAT which basically killed most of innovation in area of networking and IPv6 which is taking over 20 years to adapt, because most ISPs hold to IPv4 as long as they can because making this switch requires some work.

Well, same thing for the geniuses that made IPs 32 bit when even MACs are 48 bit.

Or, if my networking trainer at a Cisco course is to be believed, the geniuses that made IPv6 subnets contains 65k hosts at a minimum, when due to ARP requests all traffic would be dead at that scale.

Wow, this is very cool! Thank you.
