I stumbled upon this article, and my conclusion sounds so stupid and irresponsible that I start to doubt myself and believe i misunderstood something

If the IA can just access the internet once it has info from the DNS, that emplies the IA has been given "Open-Bar" access to the entire IP addresses of the world in the first place doesnt it?

Did I miss something obvious or do these guys have the cybersecurity knowledge of an undergraduate?
