Thank you very much for the clarification John.

It is good to know that there has been a policy in the past for that to happen and that BoT has understood that although ARIN could be successor of  SRI/GSI/NSI-InterNIC it would not make sense in the current or even past context at that point in time these resources to be retained by ARIN.

One point to highlight is that the communication mentions "blocks that have been voluntarily returned to ARIN" which could be understood as basically any legacy blocks had necessarily to be returned to ARIN and that IANA agrees on that or if a given legacy resource holder wishes to return it directly to IANA would it be forbidden and directed by IANA to do to ARIN ?

I have seen administratively and voluntarily dissolved corporations come
back to life, so ARIN must consider this.
Exactly… It turns out that dissolved isn’t necessarily a permanent state, and in addition “dissolved” doesn’t mean that the rights necessarily and automatically revert to the ARIN community – there may be one or more parties that has potential claim to the resources,
either via bankruptcy or provisions of the corporate wind down.

Question here John: if the resources are legacy and they were assigned before ARIN existence, these resources should ideally be reverted back to IANA which in turn should apply the Post Exhaustion Global Policy from May 6th 2021 and re-distribute these blocks to all RIRs ?

Incorrect - ARIN is the successor registry for these assignments made by SRI/GSI/NSI-InterNIC
and so they are returned to ARIN.

To the extent determined by ARIN policy and ARIN’s Board of Trustees, number resources that are revoked, returned, or reclaimed by ARIN may be returned to the IANA and then would qualify as "Any IPv4 space returned to the IANA by any means” as stated the referenced global policy.

This has occurred in the past - https://www.arin.net/vault/announcements/2012/20120611.html

Thanks!

  ARIN Returns Some IPv4 Address Space to IANA

*Posted: Monday, 11 June 2012*

Given the recent ICANN Board adoption of Global Policy Proposal - IPv4–2011, the ARIN Board of Trustees at its 6 June meeting directed ARIN staff to return to the IANA the IPv4 address blocks that have been voluntarily returned to ARIN in recent years. The total amount of space being returned to the IANA amounts to roughly a /8 equivalent and includes the large block of IPv4 addresses returned to ARIN by Interop in 2010.

Below is the final list of address space that has been returned to the IANA and this will be reflected in ARIN's database within the next few hours.

  * 45.2.0.0/15
  * 45.4.0.0/14
  * 45.8.0.0/13
