Networking Chapter 6

Which of the following are solutions to the shortage of available IPv4 addresses? (Choose all that apply.) -IPv6 -private addressing -subnetting -supernetting -NAT

-IPv6 -private addressing -subnetting -NAT

How many bits are in an IPv6 address? -32 -48 -64 -128

128

How many bits are available in an IPv6 network for creating subnets when the prefix is /48 and the host ID is 64 bits? -48 -16 -32 -64

16

A method of IP addressing in which the network and host IDs are determined by a prefix number that specifies how many bits of the IP address are network bits -​anycast addresses -​broadcast domain -​CIDR -​EUI-64 -​ISATAP -​IP prefix -​loopback address -​metric -​multicasting -Teredo

CIDR

An autoconfigured IPv6 host address that uses the MAC address of the host plus an additional 16 bits -​anycast addresses -​broadcast domain -​CIDR -​EUI-64 -​ISATAP -​IP prefix -​loopback address -​metric -​multicasting -Teredo

EUI-64

IPv6 addresses are written as 12 16-bit hexadecimal numbers separated by colons. True or False

False

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 -​anycast addresses -​broadcast domain -​CIDR -​EUI-64 -​ISATAP -​IP prefix -​loopback address -​metric -​multicasting -Teredo

Teredo

​An address type used in IPv6 to allow a one-to-many relationship between source and destination -​anycast addresses -​broadcast domain -​CIDR -​EUI-64 -​ISATAP -​IP prefix -​loopback address -​metric -​multicasting -Teredo

anycast addresses

​The bounds of a network that defines which devices must receive a packet that's broadcast by any other device -​anycast addresses -​broadcast domain -​CIDR -​EUI-64 -​ISATAP -​IP prefix -​loopback address -​metric -​multicasting -Teredo

broadcast domain

An address that always refers to the local computer -​anycast addresses -​broadcast domain -​CIDR -​EUI-64 -​ISATAP -​IP prefix -​loopback address -​metric -​multicasting -Teredo

loopback address

A value assigned to the gateway based on the speed of the interface used to access the gateway -​anycast addresses -​broadcast domain -​CIDR -​EUI-64 -​ISATAP -​IP prefix -​loopback address -​metric -​multicasting -Teredo

metric

A network communication in which a packet is addressed so that more than one destination can receive it -​anycast addresses -​broadcast domain -​CIDR -​EUI-64 -​ISATAP -​IP prefix -​loopback address -​metric -​multicasting -Teredo

multicasting

The last 64 bits of an IPv6 address are the interface identifier. What is frequently used to specify the interface identifier? -the IP address -a DHCP server -an ARP broadcast -the MAC address

the MAC address

A value used to express how many bits of an IP address are network ID bits -​anycast addresses -​broadcast domain -​CIDR -​EUI-64 -​ISATAP -​IP prefix -​loopback address -​metric -​multicasting -Teredo

​IP prefix

An automatic tunneling protocol used to transmit IPv6 packets between dual IP layer hosts across an IPv4 network -​anycast addresses -​broadcast domain -​CIDR -​EUI-64 -​ISATAP -​IP prefix -​loopback address -​metric -​multicasting -Teredo

​ISATAP
