4. Introduction about IPV6
What is the IPv6 address?
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:

• Tablet PCs Traffic control
• Gaming planes
• Voice& Video Automobiles
• security monitoring Hotspot
• Appliances PDAs

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.

10. Zero compression
Show abbreviations for the following addresses:
a) 0000:0000:FFFF:0000:0000:0000:0000:0000
b) 1234:2346:0000:0000:0000:0000:0000:1111
c) 0000:0001:0000:0000:0000:0000:1200:1000
d) 0000:0000:0000:0000:000:FFFF:24.123.12.6

• Decompress the following address and show the
complete unabbreviated IPv6address
a) 1111::2222
b) ::
