World IPv6 Day

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.

Pinterest

Hello everyone, how have we been? Today I will be sharing a very new topic. Well, not really new. It is “Pinterest”. Pinterest is a social service that allows users to create and manage carefully arranged image collections.  It is like connecting things you find interesting and then make the world see them.

Each user can make theme based image boards, tweaking them with images found online and using the “Pin it” button or uploaded from a computer. Each uploaded item is called a “Pin”. It could be a picture, a video or a discussion. Pinterest can be accessed by adding the “Pin it” button to the desktop bookmark bar, “follow me” and “pin it” buttons added to personal websites or blog pages.

  • Registration

Registration might be a bit difficult, as many of us knew when Google plus arrived, we had to be invited to actually have full access to the features and benefits. Yes, Pinterest is in the same mould. You get invitation from already registered users or directly from the Pinterest website. The registration process is simple as you can link your Pinterest account with your Facebook or twitter account.

  • Catchy or not?

Well, from my experience and reviews, Pinterest has a beautiful and attractive look and very easy to use. Lately, it is becoming a business model as it is emerging rapidly than some other social networks. Most of the content on Pinterest is about products like furniture, clothes, books and so on… The way they are arranged makes it like a very attractive catalogue and a great social experience.

What to like about Pinterest

  • Organized Inspiration: Pinterest is like the inspiration board you have in your room but this is more organized. You can upload a certain image and then on later days, find a similar image and then pin it to that specific board. The interface is easy to understand and no matter your interests, making boards will never be a problem.
  • Easy Pinning: Once you set up your Pinterest account, you will be given the steps to take in installing the “Pin it” button on your web browser. You can use this button to add a picture to your board from any website you are visiting. You can also “re-pin” your pin just like twitter’s “Retweet”.
  • Easy sharing: There is also the fact that you can share very easily on Pinterest. You can share with twitter, Facebook, Tumblr, etc.

What not to like about Pinterest

  • It is a time sucker: It takes just one visit to the Pinterest site and you will understand the reason why it is really time taking. Presently we already have social network sites that distract us and keep us up at odd hours. So if you get an addiction to this, don’t say I didn’t tell you.
  • Copyright and violations: Pinterest is a copyright nightmare for artists, photographers, bloggers, and anyone else who is interested in protecting their images from being used improperly. Pinterest members often make the mistake of pinning images they find online without giving credit to the source and linking back to its original site. Although there is the advantage of the image being linked to the source if you “pinned: the image from a website.
  • Lack of privacy settings: Pinterest banks on your interest in sharing with others and makes it nearly impossible to have a private profile. Your pinboards are open for the world to see and vice-versa. To make matters worse, users who create their Pinterest profiles through Facebook will automatically follow people with common connections because the site now has access to your online information.

For our regular visitors, there was a recent post on Instagram which is very similar to Pinterest. As we can see, social networks will always be around for a while, they aren’t going anywhere. Do we join all? Well, the real catch of Pinterest is that it can be used as a business avenue, you can sell your pins.It is fun, it is creative and interesting. Well, am going to Pin, pin and Pin on my board!

So to get an invite from us at Dashawn Enterprise, follow us on twitter @dashawnent and send your email address to us. You will be sent an invite ASAP.

Mobile Money & Cashless Society

I am sure we have all heard about mobile money and the cashless society plans going on around lately. Mobile money refers to the payment services operated under financial regulations and performed from or via a mobile device.  A cashless society talks about a system which allows individuals to acquire goods and services without the exchange of something tangible or something that can be touched, e.g. money. This doesn’t mean money is not involved; the only difference is that there is no physical effect in handling it, as it is done through a mobile phone.

Financial institutions have collaborated with mobile telecommunication companies to implement solutions that can provide a platform for transactions. In Nigeria, giants like MTN and Globacom have implemented solutions to see to the success of mobile money and a cashless society.

Mobile Money

There are four modules for mobile payment; Premium SMS, Direct Mobile Payment, Mobile Web Payment (WAP) and Contactless NFC (Near field communication).

  • The Premium SMS is a payment request via an SMS text message to a phone number to buy goods and services. A text message is sent to the seller and when he receives the text, he delivers s the goods to the buyer. This has its drawback as there is an absence of a trusted delivery system fast enough to make business smooth.
  •  Direct Mobile Billing is used during checkout at an e-commerce site. Here, a two-factor authentication is involved and a risk management system is present to prevent fraud. Benefits include security, convenience, easy, fast and proven.
  • Mobile Web Payments (WAP) where the consumer uses web pages displayed or additional apps downloaded on his mobile device to make payments. It uses Wireless Application Protocol (WAP) as underlying technology and inherits all advantages and disadvantages of WAP.
  • Contactless NFC (near Field Communication) which is used in paying for purchases made in physical states or transportation services. The consumer using a special phone equipped with a smart card waves his/her phone near a reader module. It doesn’t require any authentication to carry out any service. There are some mobile phones that make use of this feature like the Blackberry 9360 smartphone.

Recently, MTN and Globacom have come up with their mobile money platforms to bring this service to individuals in the society. Very soon, there will be lower usage of normal paper transactions and even credit and debit cards. MTN has collaborated with Fortis Mobile Money, a recently licensed mobile service provider in Nigeria for a mobile money platform. With this solution, Fortis Mobile Money will be readily available to every subscriber on the MTN Network.

Globacom also has their own solution which is called “Glo Txtcash”, in which you can transfer money to any mobile number, spend money directly from their mobile money account to pay for goods as well as buy airtime top-up for themselves and others.

Mobile Money

  From the look of things, I believe that with the investment of the telecommunication giants, there will be a great shift in carrying cash for purchase of goods and services.

SopA SagA

I know a few geeky ones would have heard about the SOPA saga. SOPA, SOPA, SOPA!
That is all that I have been coming across on the internet for the past week. For you non- geeky readers, the Stop Online Piracy Act (SOPA) is a U.S. House bill to fight online trafficking in copyrighted intellectual property and counterfeit goods.

Proposals include preventing advertising networks and payment facilities from conducting business with allegedly infringing websites, preventing search engines from linking to the sites, and requiring Internet service providers (ISP) to block access to the sites. The bill would criminalize the streaming of such content, with a maximum penalty of five years in prison.

Many of us knew about the “ Fuel Subsidy”and how removing the subsidy would make life difficult for the Masses. Yes, that is the way it sounds to us here at Dashawn Enterprise. The effect will be widespread, breaking the idea of the internet and even the chain of the internet community, thereby making it hard for the masses to get information or education online

Who will be affected by the SOPA Act?

 User content websites, like YouTube, which involves uploading and watching of videos, etc., will be affected. Imagine you go to YouTube and upload a video, and without you knowing that the video is an act of infringement, you will be blocked, even “youtube.com” will be blocked. This doesn’t make so much sense as this kills the idea of what the internet really is.

 There is also an issue of Internet security. I want to believe there will be an increase in the number of hackers in the world. This isn’t good, taking us back to the 80’s where hackers dominated as the internet was a big deal back then.

ď‚· The whole idea of a Domain Name System (DNS) will be disrupted. The DNS which is like a phone directory translates browser requests for domain names to their respective IP addresses assigned to a computer or network. The bill requests that DNS services should reject requests to translate the domain names to IP addresses. To this end, each country will have to have a DNS service to cover for a particular country.

 Finally, IP privacy will be compromised as there will be a heavy monitoring of IPs by Internet Service Providers. The monitoring will be as a result of the efforts of these ISPs (Hosts) to make sure that their users don’t visit a website with any infringing material. Every Internet user on a particular network would have his/her privacy compromised as the ISP will know every website you are visiting per time.

In conclusion, if SOPA act is passed, I won’t be able to blog freely as I want; the whole internet idea is defeated. Wikipedia, Facebook, Twitter, WordPress, BlogSpot, etc. social sites as a whole is dead. The internet will be in colonies, each colony monitoring its users and contents.

I am sure and confident this Bill won’t be passed.
