I’ve just released a small tool I’ve been working on for a while - specifically the tool gets an up-to-date list of all the IP addresses that must be allowed in order to make a ShotGrid connection. In my environment, this helps me allow only ShotGrid (and several other site-specific hosts) and block all other internet access attempts.
It includes both a function to return all the IPs queried, as well as a main module that includes how I’m utilizing it (through iptables on a linux box).
Please let me know if you find it useful, and if there are any IP sources I’ve missed. Specifically, I’m located in the Eastern US so some of the worldwide S3/amazon sources are omitted on my end. If there’s interest, it might be worthwhile to include functions that return IPs by region requested, for example.
