"The other interesting point is that at the start of 2017 the reporting systems have a divergence of some 50,000 route entries, yet by the end of 2019 this divergence has increased to some 100,000 routing entries.

This illustrates an important principle in BGP, that there is no single authoritative view of the Internet’s inter-domain routing table – all views are in fact relative to the perspective of each BGP speaker."

This is not news to me, but its always important to keep in mind

"The overall conclusions from this collection of observations are that the IPv4 network continues to grow, but as the supply of new addresses is slowing down, what is now becoming evident is the more efficient use of addresses, which results in the granularity of the IPv4 interdomain routing system becoming finer."

i.e more IPv4 /24s in the v4 BGP routing table as people sell off chunks from bigger subnets

@packetcat When I was in college, my living group owned all of 18.N.*.* for one value of N, because MIT pretty much gave one to each building.

@bstacey yep MIT is one of the orgs that got a /8 in the ye olden days

last I heard they sold off chunks from that /8 (to Amazon I think but I'm not sure)

@packetcat @bstacey yeah, you can get 18. address for aws instances in us-east-1

used to let you get free access to academic papers and stuff from MIT, although iunno if that's still true
