IPv6 Addressing

Question 1

IPv6 address is a _________.

Answer 1

128-bit address that is displayed in a hexadecimal format.

Question 2

The IPv6 Address is divided into 8

Answer 2

16-bit groups, each separated by a colon (:).

Question 3

You can replace consecutive zeros with ____

Answer 3

double colons (::) when referencing an address that has a group of zeros in the address. This process is know as compressing zeros.

Question 4

IPv6 uses three types of of addresses:

Answer 4

Unicast, Multicast, and anycast

Question 5

Unicast

Answer 5

Used for one-to-one communication

Question 6

Multicast

Answer 6

Used to send data to a group of systems

Question 7

Anycast

Answer 7

Applied to a group of systems providing a service. Clients that send data to the anycast address could have the data sent to any of the systems that are part of the anycast address.

Question 8

Three different types of unicast addresses:

Answer 8

Global unicast, site-local unicast, and link-local unicast.

Question 9

Global unicast

Answer 9

A public IPv6 address that is routable on the internet. This address type is equivalent to a public IP address with IPv4.

Question 10

Site-local unicast

Answer 10

A private address for the IPv6 protocol; the address always starts with FEC0. The site -local address cannot be used to communicate off the local site or network and is not reachable by other sites or systems on the internet.

Question 11

Link-local unicast

Answer 11

An address that is self-assigned and is used to communicate only with other nodes on the link.

Question 12

Link-local addresses always start with

Answer 12

FE80

Question 13

IPv6 loopback address:

Answer 13

0:0:0:0:0:0:0:1 or ::1

Question 14

The address for a system with no address specified

Answer 14

0:0:0:0:0:0:0:0 or (::)

Question 15

The newer version of IP is responsible for

Answer 15

Logical addressing and routing functions

Question 16

ICMPV6 Protocol is responsible for error and status information. ICMPV6 uses codes, each code indicates the type messages:

Answer 16

Codes from 0 to 127 are used by error messages, while codes 128 to 255 are for information messages.

Question 17

Multicast Listener Discovery (MLD)s

Answer 17

Is used for multicast communication.

Question 18

Neighboring Discovery (ND)

Answer 18

Replaces ARP from the IPv4 days by performing the same function, but it is responsible for neighboring router discovery, automatic address assignment, and duplicate address detection, to name a few features.
