Drawing preview
El escenario

A company operates split-horizon DNS so internal and external clients resolve the same hostname to different IP addresses; after resolution, traffic is routed through internal or gateway paths based on client source.

Qué hay en este dibujo

Lee las decisiones que hay detrás.

01

02
