Example Concept: In a split-horizon DNS setup, an organization configures its DNS servers to provide different IP address resolutions based on whether the DNS query originates from within the internal network or from an external source. For instance, an internal query for "app.example.com" might resolve to a private IP address within the organization's VPC, while an external query for the same domain resolves to a public IP address. This setup is crucial in hybrid environments to ensure seamless access to resources while maintaining security and optimizing traffic routing.
