Cisco Prime Network Registrar is a versatile and high-capacity solution designed to provide robust services for both Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS), acting with authority as a DNS server while also functioning as a caching DNS. It dramatically boosts DNS query performance, capable of managing over 20,000 DHCP leases per second and seamlessly supporting more than 130 million devices across several servers within a single deployment. The system enhances server efficiency by balancing DHCP lease renewals, distributing loads strategically across clusters, and offers various deployment methods, including image downloads, Docker containers, VM OVA, QCOW2, or pre-configured appliances. To maintain operational reliability, it integrates multiple redundancy levels with both DHCPv4 and DHCPv6 failover capabilities, in addition to providing support for high-availability DNS (HA-DNS). Customizable dashboards are available to display the current status and operational trends of both DHCP and DNS services. The extensibility of this solution is notable, as it includes a robust extensions interface alongside REST APIs, empowering users to tailor functionalities to their specific needs. Overall, Cisco Prime Network Registrar stands out as a comprehensive tool for managing network services effectively.
