SEMESTER 1 Chapter 6 Addressing the Network IPv4 V 4.0 6.1.1 How many bits are the source and destination IPv4 addresses? 32-bit source address and a 32-bit destination address What is the name for the decimal representation of the binary IP address called? dotted decimals How many bits are there between each “dot”? 8 bits What are those bits called? an octet Define the network portion of an IP address? The octets that represent a network. What is the host portion of the IP address? The octets that identify the host on a network. What does the number of bits assigned to host determine? A device on the network. 6.1.2 What is the binary range in decimal of a byte? 0 to 255 The rest of 6.1 Binary conversions will be covered in the lab meeting? Ok 6.2.1 Define a network address. The address by which we refer to the network. Define a broadcast address. A special address used to send data to all hosts in the network. Define a host address. The addresses assigned to the end devices in the network. What is the range where host addresses assigned? End devices. 6.2.1. 2 What is assigned to determine how many bits are in network bits? A Prefix Do the number of hosts that can be assigned stay the same when prefix changes? No 6.2.2. 1 How do you calculate the network value? First three octets of an address the fourth being 0 How do you calculate the first host value? Last octet of an address greater than 0 How do you calculate the broadcast address? Number of bits in last octet put at the end of a network address How do you calculate the last host address? The highest host address for a network is always one less than the broadcast. 6.2.2.

2 excellent practice for calculating the different values; you can do this until you have mastered the process. Please try it with prefix values of 24 and over so you have an example to go by. 6.2.3 Define unicast the process of sending a packet from one host to an individual host Define broadcast the process of sending a packet from one host to all hosts in the network Define multicast the process of sending a packet from one host to a selected group of hosts What is another name for a unicast address? host-to-host 6.2.3. 2 How does a host process a broadcast transmission? When a host receives a packet with the broadcast address as the destination, it processes the packet as it would a packet to its unicast address. What is a broadcast transmission used for? Broadcast transmission is used for the location of special services/devices for which the address is not known or when a host needs to provide information to all the hosts on the network.

    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.
