Front 3

List 5 improvements of IPv6 vs IPv4

Back 3

1 - QoS, built-in
2 - routing, more efficient

Front 4

IPV6 addresses are written by using _ blocks of _ hexadecimal digits

Back 4

Front 5

Each block is annotated by __ and represents a __ bit number

Back 5

:
16

Front 6

You can shorten an IPv6 address by elimnating any leading __ in blocks.

Back 6

zeroes

Front 7

How would you shorten the following address:

2001:0DB8:3FA9:0000:0000:0000:00D3:9C5A

Back 7

2001:DB8:3FA9:0:0:0:D3:9C5A

Front 8

How can you further compress the IPv6 address?
