IPv6 Vs IPv4

The Internet is broken, but don’t worry IPv6 will fix it


What is IPv6?

IPv6 is a new protocol for transferring information over the Internet.  Essentially IPv6 is a new way of assigning addresses to devices connected to the Internet.  In IPv4, or past  Internet standards, the addresses assigned follow a maximum of three numbers grouped in four like 


The best way to describe IP in “people terms” is to think of the Internet as a giant telephone system. Except instead of getting a telephone number like 703-555-5555 a communication device gets an IPv4 number like .  The problem with IPv4 is that the IP numbers, or “pc phone numbers”, are expected to run out in 2009.  Several years ago engineers came up with a “quick fix” solution called routers. 


What is a router?

Think of a router like the telephone switchboard of a company.  A call comes into a main switchboard and then the switchboard assigns an extension like 703-555-5555 Extension  105.  That’s what an IPv4 router does, it acts like a switchboard.  The problem is that routers don’t assign direct extensions to each PC because they generally have a limited number of “extensions” to give out.   Most routers assign an “in house” random IP or an “unused extension” every time you turn on your PC.  IPv6 solves this problem by being able to give each device connected to the Internet its own IP address.  In simple terms, every PC\device gets its own “phone number” so it can be called directly.


So let’s look at what an IPv6 address(or computer phone number) looks like compared to an IPv4 address.


IPv6 vs IPv4

IPv4 address format: Four groups of numbers separated by periods.  Each number cannot exceed 255 due to memory requirements.  An example of an IPv4 address is


IPv6 address format: Eight groups of numbers and letters A-F seperated by semi-colons. Each group of numbers and letters is limited to four.  An example of an IPv6 address is FEDC:BA98:7654:3210:FEDC:BA98:7654:3210 .


As you can see IPv6 offers more addresses.


Why is IPv6 Important?

IPv6 is important because IPv4 addresses are estimated to run out in 2009. IPv6 also provides a 20% increase in the speed of routing packets because routing tables and translations can be simplified.  IPv6 also assigns specific addresses to certain types of devices like media devices or unicast devices.  By knowing what type of traffic is being transmitted from devices the Internet can more efficiently decide how to transported specific data.  One good example of this is transmitting video and sound data where little feedback is needed during transmission.  If we lose a television signal for a second we can probably survive, but losing banking data for a second is a different story.


Who and Where?

In general, IPv6 will affect all areas of the world.  Developing countries will be the most affected by IPv6 address allocations.  As developing countries build their Internet infrastructure they will need to acquire IP addresses at an increasing rate.   Currently the United States is the largest holder of allocated IPv4 addresses.  The United States owns about half of the IPv4 addresses with Japan as a distance second.  Africa barely shows up in statistics for IP addresses.  It is important to note that an IP address is specific to devices not people.  As Internet devices and sensors continue to grow and become web aware each person may end up with 5 or more IP addresses.  Sample uses for IPv6 addresses are cell phones, GPS devices, laptops, TiVO, cable modems, cable TV remote boxes, remote webcams, security systems, payment devices, car computer devices, satellite radio, lighting systems, remote gaming devices, RFID keys and many more.

What software will IPv6 impact?

The largest types of software and computer devices that will be directly affected by new IPv6 assignments are Internet communication hardware, remote sensors and communication software.  In general applications such as word processing, accounting and graphic software will not be affected by IPv6, only applications that rely heavily on Internet data. Microsoft has included IPv6 in XP2 and all of its server products.  Microsoft’s new Vista product will expand the capabilities of the Microsoft operating system with a tighter coupled IPv6 core.



Most major ISP’s have already converted their main backbones to IPv6.  However only a few are offering the service to residential consumers currently.  IPv6 is being rolled out to major Internet users first.   These major Interent users include hosting providers and main Internet service providers.   The current Internet2 used by United States Universities, US Department of Defense offices and field support are currently running IPv6.  All US government agencies are required by OMB to be IPv6 compliant by 2008.


Most major router companies such as Cisco already include the Ipv6 protocol on their latest routers and Internet switches.  In most cases enabling IPv6 is as simple as turning on a switch on the router to allow IPv6 packets to be transmitted.  Some routers may require more memory to be added to handle the expanded IP addresses.  However many security programs such as firewalls and blocking software are not setup to detect IPv6 traffic.  Specific IPv6 security compliant firewalls and tracking software are required.


IPv4 is not going away.  All major Internet sources say they will keep running IPv4 and be backward to compatible to IPv4. In most cases dual protocols of IPv4 and IPv6 will be running on the same network.  In some cases IPv6 will be packaged or wrapped in IPv4 to be transmitted to IPv4 only devices.



IPv6 presents a major step forward in increasing security and eliminating the need to assign “fake” IP addresses to devices.  IPv6 provides the much needed Internet protocol to make live video and audio a reality.  The switch to IPv6 will initially be implemented in test stages with the exception of selected government and educational systems around the world.   IPv4 won’t go away, but it will be like driving an old car on the Internet highway.  The middle of 2007 is when IPv6 will mostly start impacting the market.
