What is a bit?

CH 7 pg 205

A bit is one binary digit, either a 1 or a 0.


A______ is 7 or 8 bits, depending on whether parity is used.
CH 7 pg 205



An __________, made up of 8 bits, is just an ordinary 8-bit binary number.

CH 7 pg 206



True or False the terms byte and octet are completely interchangeable, and they are typically displayed in decimal up to 255.

CH 7 pg 206



This is the designation used in routing to send packets to a remote network— for example,,, and
CH 7 pg 206

Network Address


The _____________ is used by applications and hosts to send information to all hosts on a network.
CH 7 pg 206

broadcast address


True or False The 32-bit IP address is known as a structured, or hierarchical, address as opposed to a flat, or nonhierarchical, address.

CH 7 pg 206



What are class D and E networks used for?

CH 7 pg 211

Class D (224– 239) is used for multicast addresses and Class E (240– 255) for scientific purposes.


What is the multicast broadcast range? CH 7 pg 211

multicast range is from through


Packets addressed to a unicast address are delivered to a single interface, same as in IPv4. For load balancing, multiple interfaces can use the same address.
CH 7 pg 219



These are your typical publicly routable addresses, and they're used the same way globally unique addresses are in IPv4. CH 7 pg 219

Global Unicast Addresses


Whats the difference between DHCPv4 and DHCPv6?
CH 7 pg 223

DHCPv6 supports version IPv6


What is 6to4 Tunneling? CH 7 pg 224


6to4 tunneling is really useful for carrying IPv6 packets over a network that's still running IPv4.


A___________address is assigned to a single interface, and this term is used in both IPv4 and IPv6 to describe your host interface IP address.

ch 7 pg 215

Unicast Address


An___________ is a numeric identifier assigned to each machine on an IP network. It designates the specific location of a device on the network.

IP Address


address is used by applications and hosts to send information to all hosts on a network. Examples include, which designates all networks and all hosts;, which specifies all subnets and hosts on network; and, which broadcasts to all subnets and hosts on network
ch 7 pg 206

broadcast address


In a ________ address, the first byte is assigned to the network address, and the three remaining bytes are used for the host addresses. The_________network format is as follows:

ch 7 pg 208

Class A network


In a ______network address, the first 2 bytes are assigned to the network address and the remaining 2 bytes are used for host addresses. The format is as follows:
ch 7 pg 209

Class B Network


What is the format of a Class C Network? or


is assigned to, and uniquely identifies, each machine on a network. ch 7 pg 207

host address


also called the network number— uniquely identifies each network. ch 7 pg 207

network address


The crux of ________ is that it enables multiple recipients to receive messages without flooding the messages to all hosts on a broadcast domain. However, this is not the default behavior— it's what we can do with multicasting if it's configured correctly!

ch 7 pg 214



___________broadcasts are also known as hardware broadcasts.they only go out on a LAN, and they don't go past the LAN boundary (router).
ch 7 pg 214

Layer 2


What are three of the primary transition strategies available to us.

ch 7 pg 223

Dual Stacking
6to4 tunneling


is a transition technology that gives full IPv6 connectivity for IPv6-capable hosts that are on the IPv4 Internet but have no native connection to an IPv6 network.
