Hello @Denso nakamura
Welcome to the Atlassian Community!
Per your description, I understand you are restricting your Github to connect with a restricted number of whitelisted IP ranges, so you are looking for the Ip ranges/Domains of your Atlassian Cloud applications to properly add them to the whitelist. Is that correct?
You can check in the documentation below all the IP ranges and domains used by Atlassian Cloud applications (Jira and Confluence):

Let us know if you have any questions or if you are looking for something else.
