1

Bit

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

2

Byte

A byte is 7 or 8 bits, depending on whether parity is used.

3

Octet

An octet, made up of 8 bits, is just an ordinary 8-bit binary number. A section of an ip address

4

Network address

uniquely identifies each network. This is the designation used in routing to send packets to a remote network—for example, 10.0.0.0, 172.16.0.0, and 192.168.10.0

5

Broadcast address

The broadcast address is used by applications and hosts to send information to all hosts on a network.

6

Broadcast address which designates
all networks and all hosts

255.255.255.255

7

Boradcast address which specifies all subnets and hosts
on network 172.16.0.0

172.16.255.255

8

Broadcast address for all subnets and hosts on
network 10.0.0.0

10.255.255.255

9

What is the network address of 172.16.30.56

172.16

10

Host address

assigned to, and uniquely identifies, each machine on a network. This part of the address must be unique because it identifies a particular machine—an individual—as opposed to a network, which is a group

11

What is the host address of 172.16.30.56?

30.56

12

Which octets are set aside for network and host addresses in a class A network?

Network.Host.Host.Host

13

Which octets are set aside for network and host addresses in a class B network?

Network.Network.Host.Host

14

Which octets are set aside for network and host addresses in a class C network?

Network.Network.Network.Host

15

APIPA

Automatic Private IP Addressing. With APIPA, clients can automatically self-configure an IP address and subnet mask

16

IP Range for APIPA

169.254.0.1 through 169.254.255.254

17

Subnet mask for APIPA

255.255.0.0

18

Layer 2 broadcasts

Hardware broadcasts. These are sent to all nodes on a LAN. AKA hardware broadcasts. Don't go beyond the router. All 1s, or in hex, Fs

19

Layer 3 broadcasts

Network broadcasts. These are sent to all nodes on the network. Example: ARP (Address Resolution Protocol)

20

Unicast Address

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

22

172.16.255.255 is an example of what type of address

Layer 3 Broadcast

23

255.255.255 is an example of what type of address? What is the target of the address?

Layer 3 Broadcast, all networks/all hosts

24

How many addresses will IPv6 provide?

3.4 x 10^38

25

How many bits is IPv6?

128 bits

26

0:0:0:0:0:0:0:0

Equals ::. This is the equivalent of IPv4’s 0.0.0.0 and is typically the
source address of a host when you’re using stateful configuration (DHCP).

27

0:0:0:0:0:0:0:1

Equals ::1. The equivalent of 127.0.0.1 in IPv4.

28

0:0:0:0:0:0:192.168.100.1

This is how an IPv4 address would be written in a mixed IPv6/
IPv4 network environment.

29

The global unicast address range in ipv6

2000::/3

30

The unique local unicast range in ipv6

FC00::/7

31

The link-local unicast range in ipv6

FE80::/10
