One of the startups I worked for did business with Ford. We needed info about their networks to get them connected to our service in AWS, and in the process we learned that they still use public IPs for everything. Every workstation, server, router, etc. connected to the internet from a public IP, no NAT and only protected by extremely complicated firewall rules. Their IT team must be in constant distress, or super defensive about their architecture haha






Security wasn’t the main concern in this particular case, the headache came from the fact that they were working in IP classes, and we were working in CIDRs (EC2 security groups, for example)
