Every additional route and its ASN takes up RAM in nearly _every_ router that has a DFZ (default-free zone) view. This RAM is not cheap, so regional registries are incentivized to keep the number of new registrations down.
For IPv4 there are about 1 million routing entries right now, and for IPv6 about 200k. The IPv6 routing space can reasonably scale by about 5-10x before requiring serious changes in the core routers, but that's just not a lot of entries.
- nucleardog 2y agoYeah, that thought had crossed my mind and for some reason I figured "hey, hurricane electric will give me a /48 at points all over the world, guess someone figured it out". Thinking back... no, that doesn't mean that. It's not portable and there's no reason they're not assigning from different pools at each location.
