If you’re a network administrator, at times it may seem like the IP network traffic and volume of IP addresses and devices you oversee are increasing at an unmanageable pace. On top of that, the complexity and size of IP networks continue to expand, and network operators are beginning to transition to IPv6 and introduce new technologies and services into their networks (VoIP, video, cloud computing, virtualization, etc.). Network operators need to accelerate provisioning and simplify service activation.
Given the mission-critical importance of DNS and DHCP services in today’s service provider and enterprise networks, you now face huge challenges with IP address management that must be addressed. Without a fast, reliable, and secure DNS service, subscribers’ broadband Internet access will be compromised. If DNS fails, the Internet will fail. Likewise, DHCP is a core network access technology -- every device must be assigned a unique address when connected to the network, a virtually impossible task to undertake manually.
To effectively address these challenges, network administrators need an integrated solution for DNS, DHCP, IPAM (DDI) to effectively manage IP address growth and help automate the adoption of IPv6.
And that’s just what Cisco is now providing.
As part of its service provider network management portfolio, Cisco is introducing Cisco Network Registrar 7.2 which provides an integrated, scalable, reliable solution for DDI across multiple technologies to simplify management of IP addresses and the transition to IPv6. Cisco Network Registrar is the industry’s fastest and most scalable DHCP server - able to assign more than 47,000 leases per second on a Cisco B-Series UCS platform (and 14,000 leases per second on a non-Cisco hardware platform) and support more than 50 million devices in a single customer deployment.
Cisco Network Registrar addresses your concerns for reliability with DHCP safe failover, support for High Availability DNS, and avalanche defense based on packet prioritization. The solution includes full lifecycle management for IPv4 and IPv6 and allows dual-stack deployments on a single server. Multitenant capabilities help enable cloud-based DHCP and DNS services by providing subscribers with secure IP address management and self-service control. The solution is able to be deployed in a virtualized environment and finally, with IPAM, Cisco Network Registrar administrators can control and monitor DNS and DHCP servers from a centralized location to synchronize information, reduce outages, and improve efficiency.
All told, with Cisco Network Registrar 7.2, network administrators are provided an IP address management solution that is unsurpassed in performance and reliability and is future-ready against further growth in network size, complexity and traffic volume - and the transition to IPv6.
