Support large-scale DNS operations with Cisco PNR 11.x Smart DNS for 4 million resource records. This licensing option is built for teams that need dependable name resolution across complex enterprise environments, where DNS performance and control directly affect application availability and user experience. By sizing for 4 million RRs, it gives infrastructure teams room to manage expansive zones, distributed services, and changing records without forcing constant rework. That matters when DNS is part of the control plane for hybrid networks, application delivery, and internal services that cannot tolerate avoidable lookup issues. Cisco positioning here is about operational confidence: a license tier intended for organizations that need more than a basic DNS footprint. It fits environments where record volume, governance, and consistency justify a premium entitlement rather than a minimal deployment. For procurement teams, it offers a clear path to align DNS capacity with enterprise growth and service continuity requirements.
