We need to allow some systems in a restricted subnet to access app.opsgenie.com , which resolves to more than one address, such as 104.192.142.6 , .7 , etc. Atlassian publishes a list of IP ranges in:
https://ip-ranges.atlassian.com/
but it seems to be for any Atlassian cloud-based product. I don't want to open up anything that is not needed, which of the many IPs/networks are used for opsgenie access?
