About Network Registrar
Network Registrar is a network server suite that automates managing enterprise IP addresses. It provides
a stable infrastructure that increases address assignment reliability and efficiency. It includes these
servers (see Figure 1-1 on page 1-2):
• Dynamic Host Configuration Protocol (DHCP)
• Domain Name System (DNS)
• Router Interface Configuration (RIC)
• Simple Network Management Protocol (SNMP)
• Trivial File Transfer Protocol (TFTP)
You can control these servers by using the Network Registrar web-based user interface (Web UI) or the
command line interface (CLI). These user interfaces can also control server clusters that run on different
platforms.
You can install Network Registrar in the local or regional mode:
• Local mode is used for managing local cluster protocol servers.
• Regional mode is used for managing multiple local clusters through a central management model.
A regional cluster centrally manages local cluster servers and their address spaces. The regional
administrator can perform these operations:
• Push and pull configuration data to and from the local DNS and DHCP servers.
• Obtain subnet utilization and IP lease history data from the local clusters.
• Manage the router interface configuration (RIC) server that integrates with cable modem
termination systems (CMTSs) directly from the regional cluster.
