Question 9

APIPA

Answer 9

169.254.0.1 - 169.254.255.254

Question 10

Unicast

Answer 10

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.

Question 11

Global Unicast Addresses

Answer 11

These are your typical publicly routable addresses, and they’re used the same way globally unique addresses are in IPv4.

Question 12

Link-Local Addresses

Answer 12

These are like the APIPA addresses in IPv4 in that they’re not meant to be routed and are unique for each link (LAN)

Question 13

Unique Local Addresses

Answer 13

These addresses are also intended for nonrouting purposes, but they are nearly globally unique, so it’s unlikely you’ll ever have one of them overlap with any other address.

Question 14

Multicast

Answer 14

Again, as in IPv4, packets addressed to a multicast address are delivered to all interfaces identified by the multicast address. Sometimes people call them one-to many addresses.

Question 15

Anycast

Answer 15

Like multicast addresses, an anycast address identifies multiple interfaces, but
there’s a big difference: The anycast packet is delivered to only one address— actually,
to the first IPv6 address it finds defined in terms of routing distance. And again, this
address is special because you can apply a single address to more than one interface.

Question 16

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

Answer 16

Equals ::. This is the equivalent of IPv4’s 0.0.0.0 and is typically
the source address of a host before the host receives an IP
address when you’re using DHCP- driven stateful configuration.

Question 17

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

Answer 17

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

Question 18

0::FFFF:192.168.100.1

Answer 18

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

Question 19

2000::/3

Answer 19

The global unicast address range allocated for Internet access.

Question 20

FC00::/7

Answer 20

The unique local unicast range.

Question 21

FE80::/10

Answer 21

The link- local unicast range.

Question 22

FF00::/8

Answer 22

The multicast range.

Question 23

3FFF:FFFF::/32

Answer 23

Reserved for examples and documentation.

Question 24

2001:0DB8::/32

Answer 24

Also reserved for examples and documentation.

Question 25

2002::/16

Answer 25

Used with 6to4 tunneling, which is an IPv4- to- IPv6 transition system. The structure allows IPv6 packets to be transmitted over an IPv4 network without the need to configure explicit tunnels.

Question 26

SLAAC

Answer 26

Stateless Address Autoconfiguration 7th bit

Question 27

Dual Stacking

Answer 27

This is the most common type of migration strategy because, well, it’s the easiest on us— it allows our devices to communicate using either IPv4 or IPv6.

Question 28

6to4 Tunneling

Answer 28

6to4 tunneling carrying IPv6 packets over a network that’s still running IPv4.

Question 29

CIDR

Answer 29

Classless Inter- Domain Routing

Question 30

Inside local

Answer 30

Name of the inside source address before translation

Question 31

Outside local

Answer 31

Name of the destination host before translation

Question 32

Inside global

Answer 32

Name of the inside host after translation

Question 33

Outside global

Answer 33

Name of the outside destination host after translation
