DNS Is for People – Not for IT Infrastructure

The article argues that while DNS is valuable for public-facing services, it should be avoided for internal IT infrastructure because it introduces unnecessary complexity and risk. DNS creates a critical single point of failure that can cascade across systems, as demonstrated by major incidents like the Meta outage, and can be bypassed by using direct IP addresses in configuration files or local host files instead. Additionally, DNS poses security vulnerabilities including potential spoofing attacks and data exfiltration risks, making it an unreliable foundation for internal systems.
