Unknown Outgoing IP coming from Jira Cloud (not from published outgoing ranges)

[Jan Dvorak]

I need to limit access to selfhosted gitlab from Jira CLOUD.
I have installed Gitlab intergration plugin from vendor "BigBrassBand LLC"

So I have next schema:
Jira cloud -> Gitlab intergration plugin -> Selfhosted Gitlab

But on Gitlab's side I'm getting request from ip (52.73.151.196) which is not in the range published by atlassian. Ranges is discovering with next oneliner:

curl -s https://ip-ranges.atlassian.com/ | jq -r '.items[] | .cidr' | grep -v ':'

Note: My domain is resolved only to IPv4 and Gitlab running on ipv4

My question is:
How can I get actual list of ip address where are all possible outgoing IP?

Thank you.
