ACSP Suggestion 2013.5: Provide WHOIS-RWS results in JSONP For Ease of 3rd-Party Application Development


Author: Colin Robinson   
Submitted On: 18 March 2013


WHOIS-RWS provides results in XML or JSON. Due to the same-origin policy, it is not possible for a client’s web browser to access WHOIS-RWS. Of course the server of the website that the client is visiting could act as a proxy between the client’s browser and WHOIS-RWS, but that is a waste of bandwidth.

If WHOIS-RWS could provide results in JSONP or set “Access-Control-Allow-Origin: *” to allow CORS, it would allow developers that depend on WHOIS-RWS to create easier and more efficient web applications.

ARIN believes your suggestion warrants further development and implementation. To that end, ARIN will go with the Access-Control-Allow-Origin header setting to enable this functionality as it is the best standardized approach to providing these types of services.

We do not have a scheduled implementation at this time, but will keep this suggestion open until implemented.

The ARIN Engineering team has completed the work to enable Whois-RWS Cross-origin resource sharing (CORS) using Access-Control-Allow-Origin header functionality. This enhancement is now in production. If you have any questions, please feel free to contact

This suggestion will be closed.

Thank you for your suggestion.
