Re: whois server features

...

ARIN, APNIC, and RIPE have prototypes already that are a lot easier to script than the text WHOIS.

Meaning the data structure is in place or they have a RDAP service up?

Both. ARIN's and RIPE's are based on early versions so the URLs and JSON aren't quite what RDAP says they should be yet.

If so, is it publicly accessible?

Google is your friend. R's, John
