I need to know if there is a list of IP addresses for the http://packages.elasticsearch.org repository.
Need to add it to our firewall rules so updating keeps going. We have a strict security policy.
That name resolves to an Amazon load balancer in us-east-1, so it can change ip addresses without notice. I don't think you can pin it down any more than the list of public ip addresses used by that Amazon region. Amazon publises a list of the address ranges it uses: https://ip-ranges.amazonaws.com/ip-ranges.json
They do note that this data may change several times a week
