Problem
1. The first phase of DHCP involves the client sending out a DHCPDISCOVER message. Why is this message sent out as a broadcast message, rather than a normal unicast message? List and briefly describe the other 3 messages that are exchanged.
2. Why does the Gateway in our network need several network interfaces? Why is it necessary to assign the IP addresses for these interfaces permanently in /etc/hosts rather than dynamically through DHCP?
