IPV4 & IPV6
prepared By: Ali A. Obaid
Ramadhan S. Ramadhan
Introduction
• The Internet has run out of Internet addresses... A new technology will take
its place, though. IPv4's successor is IPv6, a system that will not only offer
far more numerical addresses, but will simplify address assignments and
additional network security features.
Q:What is IPV4 ?
• A: IPv4 stands for Internet Protocol version 4. It is the underlying technology
that makes it possible for us to connect our devices to the web. Whenever a
device access the Internet (whether it's a PC, Mac, smartphone or other
device), it is assigned a unique, numerical IP address such as 99.48.227.227.
To send data from one computer to another through the web, a data packet
must be transferred across the network containing the IP addresses of both
devices.
Q:What is IPV6 ?
• IPv6 is the sixth revision to the Internet Protocol and the successor to IPv4.
It functions similarly to IPv4 in that it provides the unique, numerical IP
addresses necessary for Internet-enabled devices to communicate.
However, it does sport one major difference: it utilizes 128-bit addresses. I'll
explain why this is important in a moment.
Q: Why are we running out of IPv4
addresses?
• IPv4 uses 32 bits for its Internet addresses.That means it can support 2^32
IP addresses in total — around 4.29 billion.That may seem like a lot, but all
4.29 billion IP addresses have now been assigned to various institutions,
leading to the crisis we face today
Q: How does IPv6 solve this problem?
• A: As previously stated, IPv6 utilizes 128-bit Internet addresses.Therefore, it
can support 2^128 Internet addresses —
340,282,366,920,938,000,000,000,000,000,000,000,000 of them to be
exact.That's a lot of addresses, so many that it requires a hexadecimal
system to display the addresses. In other words, there are more than
enough IPv6 addresses to keep the Internet operational for a very, very long
time.
Q: why don’t we just switch ?
• To make the switch, software and routers will have to be changed to support
the more advanced network.This will take time and money.The first real
test of the IPv6 network will come on June 8, 2011, World IPv6 Day. Google,
Facebook and other prominent web companies will test drive the IPv6
network to see what it can handle and what still needs to be done to get the
world switched over to the new network.
Any Questions ?
