Lesson 6

Question 1

Broadcast

Answer 1

Network traffic from one network device to all other network devices on a subnet.

Question 2

Global unicast address

Answer 2

An IPv6 address used on the Internet similar to IPv4 public IP addresses. Global unicast addresses start with the first three bits as 001 or as 2 with the first number. Most have a prefix of 2001, but others are also in use.

Question 3

IPv6 prefix

Answer 3

The first numbers in an IPv6 address that identify the type of IPv6 address. For example, it can be a global unicast address (prefix of 2), a link-local address (prefix of fe80), a unique local address (prefix of fd), or a Teredo address (prefix of 2001:000).

Question 4

Link-local addresses

Answer 4

Automatically created IPv6 addresses used on local subnets. These are similar to the APIPA addresses used in IPv4. Link-local addresses start with a prefix of fe80.

Question 5

Neighbour discovery

Answer 5

An IPv6 protocol that uses ICMPv6 to discover details about the network. It can discover routers and other IPv6 parameters used on the local network.

Question 6

Teredo

Answer 6

A tunneling protocol used to encapsulate IPv6 packets within IPv4 datagrams. It allows IPv6 packets to transit through devices that aren’t IPv6 capable.

Question 7

Unique local address

Answer 7

IPv6 addresses assigned to hosts in internal networks. This is similar to private IPv4 addresses. Unique local IPv6 addresses start with fd
