Network security question: How are people restricting outbound connections based on DNS names?
For example: Server A wants to connect to cdn.network.com, and that can resolve to a huge range of IPs, so not feasible to allow list all possible outbound connections.
I vaguely remember some dns proxy / firewall magic where it tracks the answer and opens up the IP.
