If they choose to they could have (in the ARIN region) signed a LRSA,
but that's even been removed, in favor
of the now much more watered down RSA.
I believe ARCD would have been required to sign an LRSA (if they had not previously) in order to transfer the block to Amazon.
Also, a question for perhaps John here.
Organization: Amazon Technologies Inc. (AT-88-Z)
How do I know if my legacy number resources are already covered under an LRSA or not?
Typically, any legacy number resources that are covered
under an LRSA will be associated with an Organization ID ending in a “-Z”. If you have any questions regarding your legacy resources, please contact ARIN’s Registration Services Department. You may contact the Registration Services Help Desk at +1.703.227.0660
or by submitting an Ask
ARIN ticket
via your ARIN Online account.
Unless there was a clerical error somewhere, is this telling us that
44.192.0.0/10 remains classified as a legacy resource? I didn't think that was possible given that Amazon was not the original assignee.
