Interacting With ARIN


ARIN recommends that whenever possible, you make use of the functionality available within ARIN Online. For processes you wish to automate, like reporting reassignments (SWIPs), you can take advantage of the RESTful Provisioning system (Reg-RWS). If you need to continue to use email templates, note that they require an API key, which must be requested through ARIN Online.

A downloadable PDF of the table below is also available.

Note: For actions available using a Version 5 template, Version 4 templates will be accepted if they include an API key in the subject line or mail-from address, or if you associate your email address with an API key. If there is not a Version 5 template for an action, then no previous template version will be accepted. In addition, Version 3 templates are now deprecated.
