Pierre Rodriguez Intro to Networking NT1210 Morgan Date: 9.27.13 LAB 5.1 LAN Standards Exercise 5.2.5 What is the IP address of your NIC or Network adapter? What is the IP Address listed for your default gateway? A. 10.68.108.198 B. 10.68.110.1 Exercise 5.2.6 What steps are involved and how is each message sent (Broadcast to all devices or unicast to a single device)? 1. The first host contacts another host. 2. This request goes down through the OSI layers until it hits the network layer (or the Internet layer in the IP network model). At that layer, the target IP address must to be matched to a MAC or hardware address. 3. If the IP address you are trying to communicate with is not in the ARP cache, the address needs to be resolved. 4. The data request is placed on hold until the either the MAC or the IP address is resolved and an ARP request is generated and sent onto the network. 5. The packet is sent to the local hardware broadcast address, so every computer on the local network segment sees that frame and processes it.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
