CNR is a DHCP/DHCPv6 server used by cable-based and similar network service providers because of its support for fail-over between redundant servers, Dynamic DNS updates so that DHCP leases are reflected in DNS data, integration with directory services using LDAP Version 3, and ability to handle high request rates. It is also extensible.
The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol (IP) networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a client–server architecture.
Zero-configuration networking (zeroconf) is a set of technologies that automatically creates a usable computer network based on the Internet Protocol Suite (TCP/IP) when computers or network peripherals are interconnected. It does not require manual operator intervention or special configuration servers.
CNR includes a commercial DNS server from Cisco Systems usually used in conjunction with the CNR DHCP (Dynamic Host Configuration Protocol) server. It supports high rates of dynamic update. It supports high rates of dynamic update.
Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks.The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
The Dynamic Host Configuration Protocol version 6 (DHCPv6) is a network protocol for configuring Internet Protocol version 6 (IPv6) hosts with IP addresses, IP prefixes, default route, local segment MTU, and other configuration data required to operate in an IPv6 network.
If a DHCP client outside the DHCP server's subnet broadcasts an address request, it is the helper that forwards the message to the DHCP server. The server then chooses an address and sends the client a unicast message, using the helper to send the message back to the client's subnet. The address is reserved for a limited time while the DHCP ...
The network to which the supplicant needs to interact with must have a RADIUS Server (also known as an Authentication Server or an Authenticator), a Dynamic Host Configuration Protocol (DHCP) server if automatic IP address assignment is needed, and in certain configurations, an Active Directory domain controller.
