Hi Fernando,

Perhaps you are unaware but there was a time in ARIN's history where ISPs
were described in the policy manual as LIRs, Local Internet Registries,
precisely because they were expected to handle allocations to small
end-users who wanted to participate in BGP but did not qualify for an ARIN
minimum assignment. It was hoped at the time that would help improve
aggregation and routing but the technology didn't pan out that way. The
terminology has been retired (it confused people) but the behavior
underpinning the terminology remains entirely legitimate.

> An ASN received IP space to assign to other scenarios different from
> this, not to lease to someone other ASN announce pretending the first one
is a RIR.

For better or for worse that is factually incorrect.
