Comparison between IPv4 and IPv6 number of addresses
Not only computer scientists speak of IP addresses, although few people outside of that world really understand what is meant by the concept. By making a simplification -very big – this is the registration by which a device navigates through the Internet, must be unique in the entire network, otherwise there would be collisions.
most of The current traffic of the Internet runs on this protocol IPv4, who already has a few decades on top. Is a numbering system that allows you to 4.300 million different directions, combining four numbers from 0 to 255 (8-bit). Therefore, an IPv4 address consists of 32 bits. Not all addresses can be used to advantage, there are reserved ranges (such as private addresses, type 192.168.X.X) and experimental.
In the dawn of computing, no one thought that such a quantity of addresses could get to run out some day. Right now the Internet is not the sole province of computers; mobile phones, watches, cars, tablets… can also connect to the network of networks. IPv4 addresses are starting to run low, there is enough for all. The Internet providers are trying to that the general public may not be aware, as with the use of dynamic IP addresses (they change) instead of a fixed for each user.
Using IPv6 to access Google
In anticipation that such a disaster could happen any day -the exhaustion of the addresses – they devised a new protocol, IPv6, which solves the issue of addressing during a long season: 128-bit result in 340 sextillones address. Thinking to the beast, would serve to connect to the Internet multiple human colonies spread throughout the universe, and for some centuries at least.
But we do not go so far. The degree of penetration of IPv6 is small today, because IPv4 and IPv6 are incompatible with each other, and require intermediate layers to be understood. It is not as easy as to stop using IPv4 for a day, and the next to use IPv6. It is a process that takes years. The first experiments with IPv6 date back to the mid-90s.
According to Google, users who access their sites with IPv6 exceeds 10%. The deployment officer of IPv6 was the June 6, 2012, when a number of associations have agreed to offer connectivity with this protocol permanently. Of this the average citizen has not been aware, while you work the Internet has not concerned.
The greater degree of connectivity of the car is given with the mobile phones, but that will be expanded soon to other outside entities such as traffic lights or other vehicles (autonomous or not)
however, the manufacturers of cars, yes you should worry about. If the cars coming out right now on the market do not have compatibility with IPv6 there will be connectivity issues in the medium term, as or not there will be directions to them, or IPv4 will no longer be supported in some places of the network. And upside down, before 2011 was not supported the use of IPv6 in various operating systems. A day will be disconnected due to obsolescence.
right Now, the connectivity of cars to the Internet is limited, basically is reduced to take network music, news, traffic information, status of the car, maintenance information, etc More forward the connectivity will enable vehicles to communicate among themselves, and that they can connect with their immediate surroundings. We mean, how not to, technologies, car-to-car (C2C) and car to infrastructure (C2X).
The exchange of information will allow to optimize the routes of traffic, prevent accidents or blocking, etc few days Ago we talked about one of the practical applications of this technology: sync cars and traffic lights to avoid running into red lights and wasting time and fuel. We have reasons for all sides to adopt IPv6 sooner rather than later.
In a few years, there will come up with the car disconnected to the Internet (new models). The 90% of series may be connected by 2020
10 years Ago, Gerard Segarra, a chief technology of Renault, already spoke of the need to marry the connectivity on board with IPv6, and it was quite before the implementation of universal protocol again. And there will be models that don’t need a IP, but several. How? For example, a switchboard can connect to the Internet independently by reason of diagnosis or repair by remote, under appropriate security measures. The infotainment system will use its own address.
This will depend on each design, but it is a possibility. Some experts would take away importance to the problem, since the cars can connect to private networks with their own system of addresses, so as not to consume public addresses. In simpler language, it would be like to have a local network, such as the one you may have in a building, which has its own address space, independent of the Internet (private address).
When a technology is evolving at a speed so great, there is a huge risk of leaving obsolete machines with relatively little age. If the manufacturers do not begin to think long-term, the first cars connected to the Internet (the current) will begin to give many headaches to their owners, and long before you have to go to a scrap yard. What will be more severe, the failure of electronic or obsolescence that the traditional mechanical problems? Not missing much to tell.
