Minimum Allocation Size by RIRs (IPv4)

I'm trying to compile a comprehensive and up-to-date list of Minimum Allocation Sizes by the various RIRs. Any hint would be appreciated. I have so far:

ARIN: https://www.arin.net/knowledge/ip_blocks.html

APNIC: http://www.apnic.net/publications/research-and-insights/ip-address-trends/minimum-allocations (seems that they have recently changed from /22 to /24, which is not too helpful...)

RIPE NCC: http://www.ripe.net/ripe/docs/ripe-510#5

Nothing found for AFRINIC and LACNIC yet, and legacy space, too.

I have some helpful links and at least a starting point for data (a couple of years old now) in this blog entry:

Hello Fredy,

I'm trying to compile a comprehensive and up-to-date list of Minimum
Allocation Sizes by the various RIRs. Any hint would be appreciated. I have so
far:

ARIN: https://www.arin.net/reference/research/statistics/ip_blocks/

APNIC:
http://www.apnic.net/publications/research-and-insights/ip-address-trends/minimum-allocations
(seems that they have recently changed from /22 to /24, which is not too
helpful...)

RIPE NCC: http://www.ripe.net/ripe/docs/ripe-510#5

Nothing found for AFRINIC and LACNIC yet, and legacy space, too.

I made such a list some month ago and also found those links:

LACNIC: http://lacnic.net/en/registro/index.html
AfriNIC: http://www.afrinic.net/Registration/resources.htm
ARIN Micro Allocations: https://www.arin.net/reference/research/statistics/microallocations/

Hi Fredy,

Due to the transfer processes which will sustain IPv4 as the regional
free pools exhaust, the minimum allocation size can be expected to
drop to /24 in essentially all /8's within the next 24 months.

NIRs (National Internet Registries) in the APNIC and LACNIC area need
to be mapped as well as their policies sometimes differ from the RIRs
(although they are converging due to IPv4 exhaustion).

LACNIC: /24 - http://lacnic.net/en/politicas/manual3.html
NIC.br: /24 - http://registro.br/provedor/numeracao/regras.html
NIC.mx: /24 - http://www.iar.mx/jsf/static_content/services/resources_request/portable_ip_asn_wish/eligibilityCheck.jsf

/24 as minimal allocation is only for end-users and critical infrastructure.

  For ISPs (LIRs) the minimal allocation is /22.
