Here is the list of all the US ASNs networks ranked by the number of IP addresses: https://ipinfo.io/countries/us
However in the page 10, I can see some ASNs with 0 IP addresses: https://ipinfo.io/countries/us/10
My questions are:
- Can an ASN have really 0 IP addresses? How this is possible?
- More broadly, what are the requirements for creating an ASN network?
Thanks you !
