A very small introduction to IP version 6 presented by Michael Dabydeen to the 2nd Year Students in the CSI 2103 class at the University of Guyana Berbice Campus, on Wednesday Nov 7th, 2012

2. WHY IPV6
• The world is running out of Internet Address.
• IPv4 has been officially exhausted.
• “On 31 January 2011, the last two unreserved IANA /8 address
blocks were allocated to APNIC according to RIR request
procedures. This left five reserved but unallocated /8 blocks”

3. INTERNET ADDRESSES??
• Unique addressing system
to identify each node
(endpoint) on the Internet.
• Called IP Addresses

4. CURRENT ADDRESSING SYSTEM
(IPV4)
• Designed in the 70’s & 80’s
• Represented by the Decimal system
• Denoted by dot notation
Example: 192.168.2.1
Represented in Binary as blocks of 8 bits
00000000.00000000.00000000.00000000
8bits x 4 blocks = 32 bits

6. CURRENT ADDRESSING SYSTEM
(IPV4)
• Controlled by IANA - Internet Assigned Numbers Authority
• 32 bit Internet Addressing System
• Maximum Number of Address
 2 ^ 32 Address = 4, 294, 967, 296 total Address
• Address are further divided by Regions
 AFRINIC - African Internet Information Centre
 ARIN – American Registry for Internet Numbers
 APNIC – Asia-Pacific Network Information Centre
 RIPE NCC - Réseaux IP Européens Network Coordination Centre
 LACNIC - Latin America and Caribbean Network Information Centre
 Guyana Registry

7. PROBLEM?
Internet began exponential
growth.
In 1996, foresight indicated
that the internet will at some
point run out of internet
address.

8. SOLUTION?
Build a bigger Internet Space
OR
Find ways to deal with the current one
 Subnetting
 CIDR Notation
 Netmasks
 Network Address Translation (NAT)

9. BETTER SOLUTION?
Build a bigger Addressing
Space
Internet Protocol version 6
(IPv6)

10. ADOPTION
On June 6th 2011, the world did a test run of
IPv6.
On June 6th 2012, IPv6 was officially launched,
and some of the world top vendors are
currently using it.
Adoption is slow, but eventually we will all be
migrated to IPv6
How do you think this will affect us?

11. ENTER IPV6
Larger Address System for Internet Address
128 bit Addressing system
Built to accommodate 2^128 Addresss or
 340,282,366,920,938,463,463,374,607,431,768,211,456
addresses
340 Trillion Trillion
 79 trillion trillion more than IPv4
 7 billion people on Earth / About 51 Trillion Trillion IP
per perso on earth

12. FEATURES OF IPV6
 Stateless Autoconfiguration
 Anycast neighbour discovery
 Plug and Play
 Multicast
 One to many broadcast

13. ADDRESSING
 16 bit hexadecimal representation
 Blocks are seperated by colons ( : ) instead of dots .
 Hex is not case sensitive
 Zero in an address are almost meaningless and can be replaced by
double colons (: : )

2001:0db8:0000:130F:0000:0000:087c:140
B
2001:0db8:0:130F::087c:140B

14. ADDRESSING CONTINUED
CIDR
Still exists
Represented in IPv4
192.168.2.1/24
Represented in IPv6
2001:0db8:0:130F::087c:140B /48

15. IMPORTANT THINGS
Loopback Address
127.0.0.1 – IPv4
::1 or 0:0: 0:0:0:0:0:1 – IPv6
Wildcard Address
0.0.0.0 – IPv4
:: or 0:0:0:0:0:0:0:0 – IPv6

16. CONCLUSION
 IPv6 address the exhaustion of internet address
 By providing a larger 128 bit addressing system instead of 32bits
 Or 3.4 Trillion Trillion Address
 IPv6 is much improved in quality of IP Addresses
 IPv6 Address are in hexadecimal
 8 Blocks of 16 bits each
 Zeros in an IPv6 block is almost negligible
 IPv6 is currently official and occupies about 1% of the Internet.
