Hi everyone, yeah it has been a while, but I guess I am back 🙂 . Well, there is an important issue I will be discussing today. It is very important because it will be legendary and a long lasting solution to the few problems we are having in the IT world.
We know about IP Addressing…I guess…well, an IP Address of a computer or any device connected to a network; be it the internet or the intranet is the identity of the device.
For a while now, we have been using a version called Ipv4. Ipv4 is a 32 bit address, giving a total of 4,294,967,296 (232) addresses. Facts have it that as at April 2011, Asia ran out of IP addresses, Europe is close to running out, and North America is getting o that limit.
To this effect, world powers had to come together and bring up a technology. This technology has been introduced many years back, but has not been widespread. This is the Ipv6 addressing.
The Ipv6 addressing is a 128-bit addressing. So that gives us an address space of 2128 (approximately 3.4×1038) addresses. This is a whole lot and it is being introduced gradually. It might be new, unpopular and complicated to the “not-nerdy” ones, but it has its benefits.
I will be giving 5 points to back up my support for the Ipv6 technology. I will try my best to be plain in my explanations.
1. More Efficient Routing: IPv6 reduces the size of routing tables and makes routing more efficient and hierarchical. IPv6 allows ISPs to aggregate the prefixes of their customers’ networks into a single prefix and announce this one prefix to the IPv6 Internet.
2. Directed Data Flows: IPv6 supports multicast rather than broadcast. Multicast allows bandwidth-intensive packet flows (like multimedia streams) to be sent to multiple destinations simultaneously, saving network bandwidth.
3. Simplified Network Configuration: Address auto-configuration (address assignment) is built in to IPv6. A router will send the prefix of the local link in its router advertisements. A host can generate its own IP address from its MAC (physical) address.
4. Support for New Services: By eliminating Network Address Translation (NAT), true end-to-end connectivity at the IP layer is restored, enabling new and valuable services. Peer-to-peer networks are easier to create and maintain, and services such as VoIP and Quality of Service (QoS) become more robust.
5. Security: IPSec, which provides confidentiality, authentication and data integrity, is baked into in IPv6. Because of their potential to carry malware, IPv4 ICMP packets are often blocked by corporate firewalls, but ICMPv6, the implementation of the Internet Control Message Protocol for IPv6, may be permitted because IPSec can be applied to the ICMPv6 packets.
So there are probable questions to ask….
Q: So why don’t we just switch?
A: The depletion of IPv4 addresses was predicted years ago, so the switch has been in progress for the last decade. However, progress has been slow — only a small fraction of the web has switched over to the new protocol. In addition, IPv4 and IPv6 essentially run as parallel networks — exchanging data between these protocols requires special gateways.
To make the switch, software and routers will have to be changed to support the more advanced network. This will take time and money.
Q: How will this affect me?
A: Initially, it won’t have a major impact on your life. Most operating systems actually support IPv6, including Mac OS X 10.2 and Windows XP SP 1. However, many routers and servers don’t support it, making a connection between devices with IPv6 addresses to routers or servers that only supports IPv4 impossible. IPv6 is also still in its infancy; it has a lot of bugs and security issues that still need to be fixed, which could result in one giant mess.
Nobody’s sure how much the transition will cost or how long it will take, but it has to be done in order for the web to function as it does today.
To popularize this technology, there was World IPv6 Day that held last year on June 8, in which world giants, Google, Facebook, etc ran on IPv6 solely on that day and it ran very fine.
World IPv6 day is holding again on Wednesday, 6th of June, 2012 and many more giants are going to be involved.
