IPv6

Question 1

IPv6 benefits

Answer 1

Larger address space
No broadcasts
No fragmentation
Can coexist with IPv4
Simplified header

Question 2

Dual Stack

Answer 2

Simultaneously runs both the IPv4 and IPv6 protocols on the same network devices

Question 3

Tunneling

Answer 3

Allows an existing IPv4 router to carry IPv6 traffic

Question 4

IPv6 address

Answer 4

Uses hexadecimal digits and allows the use of shorthand notation

Question 5

IPv6 shorthand

Answer 5

Example:

2018:0000:0000:0000:0000:0000:4815:54ae

can be simplified to…

2018:0:0:0:0:0:4815:54ae

Which can be further simplified using the double column rule (if you have a lot of zeroes together they can be replaced by a double colon, whis can only be done once in a IPv6 address)

2018: :4815:54ae

Question 6

Unicast Address

Answer 6

Used to identify a single interface

Globally-Routed: Similar to IPv4’s unicast class A, B, and C addresses and begins with 2000-3fff

Link-Local/Local Use: Used like a private IP in IPv4 that can only be used on the local area network and begins with fe80

Question 7

Stateless Address Autoconfiguration (SLAAC)

Answer 7

Eliminates the need to obtain addresses or other configuration information from a central server

Question 8

Multicast Address

Answer 8

Used to identify a set of interfaces and begins with FF

Question 9

Anycast Address

Answer 9

Used to identify a set of interfaces so that a packet can be sent to any member of a set

Question 10

Extended Unique Identifier (EUI)

Answer 10

Allows a host to assign itself a unique 64-bit IPv6 interface identifier called EUI-64

Question 11

DHCPv6 Protocol

Answer 11

Allows DHCP to automatically assign addresses from a DHCPv6 server

Question 12

Neighbor Discovery Protocol (NDP)

Answer 12

Used to determine the Layer 2 addresses that are on a given network
