[arin-tech-discuss] Does it make sense to forego RWhois and move to RESTful API for all customer assignments?

Thanks for your questions. My response are in-line below:

While we don't publish our limits, the use case you have outlined here is
well within normal usage of Reg-RWS. There should be no problem with the
load you are describing.

Yes, we should be able to handle it.

I can't actually speak for what others are doing with Reg-RWS, but we have
certainly seen a big rise in the number of transactions via RESTful calls.

When we redesigned our systems to accommodate Reg-RWS we did take into
account the ability to have multiple assignments for a customer. While
some work is still required on our end to allow this capability, it is not
onerous. If you would like to see ARIN prioritize this capability, the
official method for getting it in front of our management team is to
submit a suggestion via the ARIN Consultation and Suggestion Process
(ACSP). You can find the link to submit an ACSP here:

Thanks for your questions. Let me know if you have any follow up comments
or questions.
