ARIN RDAP Bootstrap Server Change of Address

Posted: Wednesday, 16 December 2020

As previously announced on 21 November 2020, ARIN is changing the address of our Registration Data Access Protocol (RDAP) bootstrap server from https://rdap.arin.net/bootstrap to https://rdap-bootstrap.arin.net/bootstrap. A bootstrap server is used to forward queries from users seeking registration data for Internet resources to another server that can provide more detailed registration information about that resource. The address of the bootstrap server is used in the “query URL” sent from a client application or entered into a command-line query by a user.

ARIN has set up a redirect to automatically route queries from the old URL to the new URL when support for the old URL is ended. The old URL will be retired on 30 June 2021, and the redirect will be active. However, it is important to note we can’t guarantee the redirect will be respected by all clients. In order to avoid any problems, queries should be changed to use the new URL, https://rdap-bootstrap.arin.net/bootstrap, as soon as possible.

More information about how the bootstrap URL works and this upcoming change can be found on TeamARIN at https://teamarin.net/2020/12/11/buckle-up-change-of-address-coming-for-arins-bootstrap-server/. If you have questions or comments about this change, please submit an Ask ARIN ticket using your ARIN Online account, or contact the Registration Services Help Desk by phone Monday through Friday, 7:00 AM to 7:00 PM ET at +1.703.227.0660.
