How is 20M IPs 9% of all IPv4 hosts? That works out to something like 220M IPv4 hosts, when I'd naively think there should be more like 4B or so.

- Hikikomori 1y agoMany are reserved, not in use or even advertised.
- wutwutwat 1y agoYet they are still part of the “all ipv4” address space, so either the percentage is wrong or the use of “all” is a lie here.
- Hikikomori 1y agoNo, it's hosts, something different from just all IPv4.
- flerchin 1y agoYou're really confident about this, but I just can't find where hosts is different than addresses when we're talking about IPv4.
- Hikikomori 1y agoYou see how you can have an IP address that is not assigned or used on something? So amount of IPv4 addresses > IPv4 hosts.
