How DNS reduces network complexity

Intelligent Networking reduces the need for complicated forwarding rules and duplicate name records by giving administrators control over resolution pathways so queries are handled in a customer-defined sequence. Instead of creating multiple forwarding rules or maintaining duplicate DNS entries to reach different services, the system directs queries through the chosen resolution order, simplifying DNS configurations. This centralized control of resolution eliminates workarounds that typically cause duplication and complexity while ensuring queries consistently resolve to the intended destinations.

Resolving queries in a customer-defined sequence means administrators specify the order in which resolution sources or pathways are consulted when answering DNS queries. This approach ensures that preferred or trusted services are queried first, while secondary sources are only used if needed. The benefit is more predictable and optimized routing behavior, reduced configuration overhead, and the ability to prioritize direct access to trusted services, improving performance and operational clarity without relying on ad hoc forwarding rules.

Intelligent Networking enables internet breakout by routing traffic directly to trusted internet services rather than forcing all traffic through centralized or private MPLS links. By controlling resolution pathways and directing queries to chosen external services, the solution allows sites to access internet-based resources locally when appropriate. This bypasses costly MPLS circuits for traffic that does not require transit over private links, lowering WAN costs while maintaining trust and control over which services receive direct access.
