Net-110 Chapter 9

Front 1

An IPv4-to-IPv6 transition protocol that provides automatic tunneling of IPv6 traffic over an IPv4 network. It can handle host-to-router or router-to-host tunneling but is most often used to create a router-to-router tunnel.

Back 1

6to4

Front 2

A method of automatic IP address assignment that occurs when a computer can't contact a DHCP server; uses the range 169.254.1.0 through 169.254.254.255.

Back 2

Automatic Private IP Addressing (APIPA)

Front 3

A packet addressed to all computers on the network.

Back 3

broadcast

Front 4

The bounds of a network that defines which devices must receive a packet that's broadcast by any other device; usually an IP subnet.

Back 4

broadcast domain

Front 5

A method of expressing an IP address in the format A.B.C.D/n; n is the number of 1 bits in the subnet mask or the number of bits in the network ID.

Back 5

CIDR notation aka Classless Interdomain Routing

Front 6

The use of IP addresses with their default subnet masks according to their address class: A, B, or C.

Back 6

classful addressing

Front 7

The use of IP addresses without requiring the default subnet mask.

Back 7

Classless Interdomain Routing (CIDR)

Front 8

The IP address of the computer a packet is sent to.

Back 8

destination IP address

Front 9

The current architecture of the IPv6 protocol in Windows, in which both IPv4 and IPv6 share the other components of the stack.

Back 9

dual IP layer architecture

Front 10

An auto-configured IPv6 host address that uses the MAC address of the host plus an additional 16 bits.

Back 10

Extended Unique Identifier (EUI)-64 interface ID

Front 11

An automatic tunneling protocol used to transmit IPv6 packets between dual IP layer hosts across an IPv4 network.

Back 11

Intra-Site Automatic Tunnel Addressing Protocol (ISATAP)

Front 12

Similar in function to the IPv4 APIPA addresses, link-local IPv6 addresses begin with fe80, are self-configuring, and can't be routed.

Back 12

link-local IPv6 address

Front 13

A reserved name that corresponds to the loopback address, 127.0.0.1.

Back 13

localhost

Front 14

A binary operation in which there are two operands; the result is 0 if either operand is 0 and 1 if both operands are 1.

Back 14

logical and operation

Front 15

The IP address 127.0.0.1, which always refers to the local computer and is used to test the functioning of TCP/IP.

Back 15

loopback address

Front 16

A value assigned to the gateway based on the speed of the interface used to access the gateway.

Back 16

metric

Front 17

A network communication in which a packet is addressed so that more than one destination can receive it.

Back 17

multicasting

Front 18

A process that translates the source or destination IP address in a packet to a different value; often used to allow using private IP addresses while connected to the Internet.

Back 18

Network Address Translation (NAT)

Front 19

An 8-bit value; a number from 0 to 255 that's one of the four numbers in a dotted decimal IP address.

Back 19

octet

Front 20

The IP address of a computer that's sending a packet.

Back 20

source IP address

Front 21

A 32-bit dotted decimal number consisting of an unbroken series of binary 1 digits followed by an unbroken series of binary 0 digits. Used with an IP address to determine the network ID.

Back 21

subnet mask

Front 22

A process that reallocates bits from an IP address's host portion to the network portion, creating multiple smaller address spaces.

Back 22

subnetting

Front 23

A process that reallocates bits from an IP address's network portion to the host portion, effectively combining smaller subnets into a larger supernet.

Back 23

supernetting

Front 24

An automatic IPv6-over-IPv4 tunneling protocol that solves the problem of 6to4's requirement of a public IPv4 address and the inability to traverse NAT routers.

Back 24

Teredo

Front 25

A network protocol suite designed to deliver data packets to computers on any scale of network, from a small two-computer LAN to the worldwide Internet.

Back 25

Transmission Control Protocol/Internet Protocol (TCP/IP)

Front 26

A common network protocol technique that allows transmitting a packet in a format that would otherwise be incompatible for the network architecture by encapsulating the packet in a compatible header format.

Back 26

tunneling

Front 27

An address in a unit of network data intended for a single destination computer.

Back 27

unicast address

Front 28

An address for devices on a private network that can't be routed on the Internet.

Back 28

Unique local IPv6 address
