The market for IPv4 addresses is ultimately a band-aid solution because it affects routability. The more efficient such a market becomes at distributing addresses topologically, the less efficient packet routing becomes.
IPv4 markets are a dead-end and are no substitute for a real solution.

It's a matter of putting in more megabytes of memory for the BGP tables. We could shatter the network into 15 million /24s and still be able to route everything efficiently.
- tedunangst 10y agoThere are more than a few old routers still in use, RAM maxed out, that are bumping into their limit. Whenever an aggregated net gets accidentally split, they start failing.
- Dylan16807 10y agoOn the other hand a lot of those failed at the same time two years ago when active BGP entries went over half a million, so now's a better time than usual to add a few entries. For reference, there's about 630k active BGP entries, with 50k more per year. It would only accelerate the death of those routers by six months, 24k entries, to split up everything larger than /16.
