IPv6 and MAC Addresses

Question 1

IPv6 loopback address

Answer 1

::1

Question 2

How to broadcast to all devices on a single logical network using MAC Address

Answer 2

FF:FF:FF:FF:FF:FF

Question 3

IPv6 format

Answer 3

8 4-digit Hexadecimal numbers.

note* Divided into 8 16-bit blocks that are converted to Hexcadeciaml

e. g
2001: 0000:3228:DFE1:0063:0000:0000:FEFB

Can be simplified to
2001:0:3228:DFE1:63::FEFB

Question 4

IPv6 Simplifying rules

Answer 4

Leading Zeroes can be omitted. e.g 2001:0063 = 2001:63

One group of consecutive 0’s can be replaced by a double colon e.g DFE1:0063:0000:0000:FEFB becomes DFE1:63::FEFB

Answer 5

2001:2000 to 3FFF

Equivalent to public addresses on IPv4 networks
