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 ...

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.
Information about the IOS version and feature-set running on a Cisco device can be obtained with the show version command. [6] Most Cisco products that run IOS also have one or more "feature sets" or "packages", typically eight packages for Cisco routers and five packages for Cisco network switches.
The ipconfig command supports the command-line switch /all. This results in more detailed information than ipconfig alone. An important additional feature of ipconfig is to force refreshing of the DHCP IP address of the host computer to request a different IP address. This is done using two commands in sequence.
The DHCP server permanently assigns an IP address to a requesting client from a range defined by an administrator. This is like dynamic allocation, but the DHCP server keeps a table of past IP address assignments, so that it can preferentially assign to a client the same IP address that the client previously had. Manual allocation
