Hi,
I'm not entirely sure what you're trying
to do. But if you need a new redirect added to send users to as part of
the OAuth process, you'll just need to registered the URL as a redirect
URI, the ip address is not necessary. If it's the same URL as before just on a different server you don't need to do anything. If it's a new redirect URI, just sent it to support and they'll register it to your credentials.
If that doesn't address you're question, please follow up through
sup...@orcid.org since they have the background information about what you're asking for. I can't find any active tickets from this email address,
luispedr...@gmail.com, in the support queue but if you follow and mention my name they can pass your request on.
