Get Ready for New Templates

Posted: Tuesday, 23 November 2010

In early 2011, ARIN will be releasing updated templates (Version 5) when we change systems in order to support per-delegation management of nameservers and provision secure delegations through Domain Name System Security Extensions (DNSSEC). This new delegation management system will be available through ARIN Online only, so we will be releasing a new set of templates that will also include an API key field for added security and authentication. The nameserver fields and the optional resource contact section are also being removed from the Version 5 templates. The new templates are available for preview at:

For those who continue to use the version 4 templates, the new system will ignore nameserver changes submitted via template and will ignore any resource POCs added on Detailed Reassignment or Reallocation templates.  Please note that version 3 templates will not be supported after the new templates are released, so if you are still using version 3, please plan accordingly.

Because the current system is not yet ready to accept the new templates, please continue using the current template set until further notice. After the version 5 templates are released, all new requests should be submitted using these revised templates. The new system is backward compatible, so ARIN will continue to accept the version 4 templates to allow customers using scripts sufficient time to update their software. If you continue using version 4 templates after version 5 is released, you must include an API key in the subject line or associate your email address with an API key.

For details on this and other uses for API keys, please refer to:

ARIN encourages all customers to transition to using ARIN Online to modify your resources as these features are released because they will allow your modifications to be reflected immediately in our database.  We will continue to provide and support templates for those who are unable to use ARIN’s Web interface.

We encourage you to learn more about all of the projects in development; details are available at:
