Is it possible to use Static IP for an Atlassian Cloud instance?
Platform Notice: Cloud Only - This article only applies to Atlassian apps on the cloud platform.
Summary
When working with custom script automations and integrations, you will need to use the external IP address from Atlassian Cloud instances in order to make this work. Since Atlassian currently uses a mix of our own IP addresses and others provided by third parties, you might wonder if it's possible to use a Static IP address from your cloud instance instead in order to make your custom script work.
It's not possible to specify a unique Static IP for your cloud instance. This could cause issues with other integrations and services Atlassian works with. This applies to all of our cloud products, including Jira, Jira Service Management, Confluence, and Bitbucket
Atlassian Cloud IP ranges and domains are documented here: Atlassian Cloud IP Ranges and Domains
Atlassian cloud subdomains
Atlassian products use domains with many levels of subdomains under all the listed top-level domains.
For example, permit entry from *.atl-paas.net to allow both avatar-management--avatars.us-west-2.prod.public.atl-paas.net and jira-frontend-static.prod.public.atl-paas.net.
Additionally, you will need to ensure that top-level domains themselves are also permitted, not just their subdomains.
For example, *.atlassian.com should be used to permit both id.atlassian.com and atlassian.com.
