ARIN requires organizations to submit information for all IPv4 reassignments of /29 and larger and IPv6 reassignments of /64 or shorter prefix within seven days of the subdelegation

https://www.arin.net/resources/request/reassignments.html

• IPv4 Reassign-Simple

Used to subdelegate IP addresses to a customer that does not need to:

• subdelegate the addresses to their own customers
• maintain their own in-addr.arpa delegation
• display their own point of contact (POC) information

It can also be used to change the customer name and address information (but not the range) on an existing simple reassignment and to remove simple reassignments. It is submitted by an ARIN Online user account linked to the parent organization’s Admin or Tech POC, or the Tech POC for the resource.

 

We need to create an API key to be used in the template that is sent by Email to ARIN.

To do so go to Web Account à API Key Management

 

Here are some excerpts from the URL IPv4 Reassign-Simple
