  Short Bytes: IPv6 is the replacement for the IPv4 which is going to run out of its address space soon. In this article, I have tried to elaborate the differences between the two protocols. IPv6 is better in many aspects but it is not backward compatible with the IPv4 which can be considered as its drawback. T he internet is a gigantic network of computers across the globe. Billions of devices communicate with each other on daily basis to send and receive data. For instance, when you access a website, you’re communicating with the server computer hosting the website. You send a request for the website and the server sends the relevant data to you.You just don’t bump into a random server and start requesting for website data. You type the website’s name in your web browser, which, then asks the DNS server to resolve the IP address of the server where the website is hosted. Then a connection is established with the server and a request for website data is ...

Short Bytes:  Ever wondered  why 127.0.0.1 IP  address is assigned to localhost? Why not some other IP address like 121.9.1.1 or anything else? The answer to this question lies in the fact that by 1981, 0 and 127 were the only reserved Class A networks. As 0 was used for pointing to a specific host, 127, the last network number, was left for loop-back IP address or localhost. Y ou might have definitely heard of 127.0.0.1. You also might be knowing that 127.0.0.1 points to localhost. But, why is localhost ‘s IP address 127.0 .0.1. why not something else? Before trying to answer that question, let me tell you a little bit about how does it work. This address is used to establish a connection to the same computer used by the end-user. When we deal with IPv6 address, it’s defined using the connotation of ::1. As IPv6 addresses take over, localhost will be more commonly know as 0:0:0:0:0:0:0:1. How does 127.0.0.1 work? Why is it called so? ...

Short Bytes:  A new BitTorrent feature has been announced which is designed with a goal of maintaining a sharing ratio of 2:1 in a swarm. The confusing Altruistic Mode feature will make sure that your share more and download less. B itTorrent Inc. has added a new feature that’s strange, confusing, and interesting at the same time. Known as Altruistic Mode, the features promotes the philosophy of giving more taking less on the torrent network. The Altruistic Mode is designed to make sure that your sharing ratio remains more than 2:1 i.e. while downloading a torrent, you upload 2Gb data for every 1GB download. Many of the loyal torrent users seed to benefit the network and the download speed of other users. But BitTorrent says that this does not guarantee a 2:1 ratio. That’s where the Altruistic Mode comes handy and helps a swarm. “Because of this Altruistic Mode downloads will often never complete,” writes Bram Cohen, the creator of the BitTorrent protocol. In a blog p...

Short Bytes:  Nokia has achieved 1 terabit/sec data transmission speeds in Germany. Its subsidiary, Nokia Bell Labs worked in collaboration with Deutsche Telekom and the Technical University of Munich and developed PCS (Probabilistic Constellation Shaping) to enhance network speeds. N okia may have departed from the mobile market but many of us are unaware of the true potential of the Finnish corporation. Nokia’s acquisition of Alcatel-Lucent last year also welcomed Bell Labs (now Nokia Bell Labs) to become a part of the Nokia family. Bell Labs was founded in 1925 by Alexander Graham Bell who invented the first working telephone. Nokia Bell Labs, along with the Techincal University of Munich and Deutsche Telkom T-Labs, has been working on a network speed enhancement method. Known as Probabilistic Constellation Shaping (PCS), the technique, which won the Bell Labs Prize, can enable data transmission over a fiber connection at 1 terabit per second. As of now, Google’...

Short Bytes:  A new Ethernet standard IEEE 802.3bz has been released which boosts the theoretical bandwidth over the existing twisted pair copper wires to 2.5Gbps (2.5GBASE-T) and 5Gbps (5GBASE-T). That’s five times the current theoretical bandwidth achieved on cables designed according to the 1000BASE-T standard. T he IEEE has released a standard for the copper wire cables, 802.3bz. The new standard 2.5GBASE-T and 5GBASE-T Ethernet. The NBASE-T Alliance released a specification in November 2014 that’s compatible with the 802.3bz standard. Up until now, our wired networks have been confined to 1Gbps speed cap as per the widely implemented 1000BASE-T (IEEE 802.3ab). Now, the theoretical speeds are going to make a significant leap. The 802.3bz standard has boosted the speeds to 2.5Gbps and 5Gbps up to 100m length on the same Cat5e and Cat6 copper wires currently used. The perks are only in case of the wires. Large organizations having thousands of meters of...
