Implementing IP Addressing Services. Objectives: Configure DHCP in an enterprise branch network, Configure NAT on a Cisco router, Configure new generation RIP (RIPng) to use IPv6. Every device that connects to a network needs an IP address. Network administrators assign static IP addresses to routers, servers, and other network devices whose locations (physical and logical) are not likely to change. Administrators enter static IP addresses manually when they configure devices to join the network. Static addresses also enable administrators to manage those devices remotely....
