#IANA's Well-Known URIs ( https://www.iana.org/assignments/well-known-uris/well-known-uris.xhtml ) show how modern infrastructure is expected to work. #Automation, #ZeroTouch provisioning, and #ZeroTrust rely on predictable /.well-known/* endpoints and assume trustworthy #DNS resolution.

Discovery has moved up the stack and spans multiple layers while DNS remains the foundation. Failures surface elsewhere, when DNS is the root cause, making troubleshooting harder and turning “boring DNS” into a prerequisite for automation and architectures.
