Cisco PNR R10 DNS SIA Spare 3 Yr, 8 Million RRs | Support Warranty — PNRSO-10-DNS-2M

Keep DNS operations covered with a Cisco support term built for environments that depend on stable name resolution. PNR R10 DNS SIA Spare 3yr - 8 Million RRs provides a defined 3-year support period for the supported DNS platform, aligning coverage with deployments that manage substantial record volumes. For infrastructure teams, the value is not just entitlement management. It is continuity. When DNS sits on the path of authentication, application access, and internal service discovery, support coverage becomes part of operational risk control. This term helps maintain access to Cisco-backed assistance for the specified platform and record capacity, reducing uncertainty during incidents and planned maintenance windows. The 8 million RRs designation makes this a fit for larger DNS footprints where lower-tier coverage may not match the scale of the environment. For procurement teams, the fixed term simplifies renewal planning. For architects, it supports a cleaner lifecycle strategy around a critical control-plane service. If DNS availability is a dependency, this coverage helps keep the support path clear.
