FINAL REMINDER - ARIN Email Template Retirement Scheduled for 3 June 2024

Posted: Monday, 13 May 2024

On 3 June 2024, ARIN will retire SWIP email templates for reporting reallocations and reassignments as described in the community Consultation conducted in November of 2023. After 3 June 2024, ARIN will not accept or respond to email templates.

We recognize this change is significant and have several alternative options for submitting reassignment information. To facilitate a smooth transition, we encourage users to explore ARIN’s Reg-RWS service, a secure and efficient means of interacting with ARIN’s database.

Those who do not need to automate reallocation and reassignment submissions may find it convenient to use ARIN Online to report this information to ARIN.

For organizations who are unable to utilize Reg-RWS or ARIN Online, or for those who prefer to continue composing reassignment information in email templates, ARIN has provided an open-source template processor that customers may run within their network. This software will allow users to convert email templates to REST calls compatible with Reg-RWS. This open-source template processor was released on GitHub on 1 November 2023, and is no longer maintained by ARIN post release. If you wish to use this product beyond its initial release, you will be able to fork the repository and maintain it as your needs require. To learn more, please visit:

If you have questions about this transition, or need assistance using Reg-RWS, please contact us by submitting an Ask ARIN ticket or chatting with us using ARIN Online, or calling the Registration Services Help Desk at +1.703.227.0660 (Monday-Friday, 7:00 AM – 7:00 PM ET).
