Hi David, I like research but what would the RIRs study? The percentage of the 2021 Internet reachable from a station assigned a 240/4 IP address? Suppose it's 95%? Or 50%? Is there a difference? Neither one is enough to deploy the addresses for 2021 global use.
5. Armed with hard data on the usability of the 240/4 /8s allocated, people can scream past each other much more authoritatively on the topic of what to do with 240/4.
Which is not particularly valuable. We already know the addresses are dysfunctional on the 2021 Internet. There's no credible disagreement on that point. We don't particularly need to know it more authoritatively. What we need to know more authoritatively is: IF we tell vendors and operators to expect those addresses to come into use and alter their equipment and configurations accordingly, -how long- will it be until the addresses are usable on the Internet. 2026? 2031? 2051? That research could be valuable, but it can't usefully start until:
1. Move 240/4 from "reserved" to "unallocated unicast"
So maybe instead of
2. Wait 10 years
It's
2. IAB or IESG requests the IANA team to delegate one of the 240/4 /8s to the RIRs on demand for experimental purposes for a fixed period of time
But that still starts with:
1. Move 240/4 from "reserved" to "unallocated unicast"
