A client device on an Ethernet segment needs an IP address in order to communicate on the network. A DHCP server with IP address 192.168.1.1 has been configured and enabled on the network. How will a client device obtain a usable IP address for this network?
- Send a DHCPREQUEST packet to IP address 255.255.255.255.
- Send a DHCPACK packet to the default gateway address.
- Send a DHCPDISCOVER message to physical address FF-FF-FF-FF-FF-FF.
- Use a statically configured IP address from the pool of IP addresses that is offered by the DHCP server.
Answers Explanation & Hints:
Like IP addressing, there is also a special MAC address for broadcast purposes: FF-FF-FF-FF-FF-FF. When a DHCP client needs to send a DHCP Discover message in order to seek DHCP servers, the client will use this MAC address as the destination MAC address in the Ethernet frame. It does this because it has no knowledge of the IP and MAC addresses of DHCP servers.
