Last Wednesday the RIPE NCC launched the IP Analyser as a production service:

The application gives an overview of all your allocations, assignments, free space and invalid assignments in a user friendly web interface. It can also give a suggestion when you want to assign a free block:

We also offer an API that serves the IP Analyser data in JSON or plain text format. With plain text, we are trying to mimic the "asused" format as much as possible, but with JSON, we're actually entering new waters. 

The JSON structure we defined is based on our best guesses and limited user feedback during the beta period. Moving forward, I would like to know if it useful for you and contains all data you need for your IP address management. If there is data missing or it takes a lot of effort to derive certain data, please tell me. Furthermore, I want to know if there is any interest in XML format.

The documentation or the IP Analyser API is here:

In addition, there is a My Resources API which serves all your resource data in JSON and XML:

Thanks for any feedback you may have!

Cheers,

Alex
