4. Introduction about IPV6
1. What is the IPv6 address?
2. An IPv6 address is 128 bits or 16 bytes (8 Octets ) long as
shown in this figure. The address length in IPv6 is four times
the length address in IPv4
Slide 4

5. Benefits about IPV6
1. Routing Aggregation
2. Auto configuration of addresses
3. easier allocation of address blocks
4. flexibility of ISPs to subdivide blocks for customers
5. embedded quality of service (Qos) to support services like
VoIP &IP video.
IPv6 longer address length is the need for:

7. comparing between IPv4&IPv6
1) If you are using Internet or almost any computer network you will likely
using IPv4 packets. IPv4 uses 32-bit source and destination address fields.
We are actually running out of addresses but have not fear, the Internet
Engineering Task Force (IETF)is here with IPv6.
2) The IPv6 packet doesn't look much like its IPv4 cousin, except for the
leading version field. The IPv6 address fields are 128-bits. The larger
address space is one reason to migrate to IPv6 but there are many more
differences that give IPv6 an advantage. For example, the header
checksum field has been eliminated because transport reliability has gone
up and its overhead was unnecessary.

• Find the interface identifier if the
Ethernet physical address is (F5-
A9-23-14-7A-D2) using the
format we defined for Ethernet
address.

• We only need to change the seventh bit
of the first octet from 0 to 1 insert two
octet FFFE and change the format to
colon hex notation. The result is
F7A9:23FF:FE:FE14:7AD2 in colon hex.

• An organization is assigned the block
2000:1456:2472/48. what is the
CIDR notation for the blocks in the
first and second subnets in this
organization?

20. Zero compression
• Theoretically the first and second subnets
should use the block with subnet identifier
000116 and 000216. This means that the
block are
• 2000:1456:2472:00001/64
and
2000:1456:2474:0002/64

• An organization is assigned the block
2000:1456:2472/48. what is the IPv6
address of an interface in the third
subnet if the IEEE physical address
of the computer is (F5-A9-23-14-7A-
D2)16

Slide 21

22. Zero compression
The interface identifier is F7A9:23FF:FE14:7AD2
if we add this identifier to the global prefix and the
subnet identifier we get
