It is beyond discussion that the full implementation of IPv6 in all Internet services and infrastructures will take place sooner or later. However, a harsh reality has knocked our door a few months ago. The Number Resource Organization (NRO) has warned that the available free IPV4 address space has fallen below 10%, which is considered a critical level. From this information, the organization has considered the implementation of IPv6 vital if we need to continue with the development of the Internet. IPv4 addresses, with a length of 32 bits, helped to define the Internet address space that we have been using so far, and have 4,294,967,297 possible IP addresses. In January 2010 the barrier of less than 430 million IP addresses not yet allocated is what has caused this warning. If we run out of IPv4 addresses this means a halt to the spread of the Internet which has grown in a steady pace since 1989, and that is the main business infrastructure in today's technology. The key to overcoming this limitation: the global adoption of IPv6. However, many experts argue that implementing NAT may extend the life of IPv4 a few more years. Personally, I believe that further delaying the full migration to IPv6 simply postpones the implementation of a technology that has long been awaiting implementation, which will enable significant improvements in the operation of the Internet while offering new services. The implementation of NAT at the ISP level will only result in limiting the services available, and also hinder the seamless operation of the Internet when IP addresses are translated. Moreover, major Internet sectors are already operating with IPv6 (China, Japan, parts of Europe and USA), and Internet infrastructure design is ready to support the migration: there is an international backbone running in IPv6, DNS services have updated their record structure etc… in fact, there is already a fully operational IPv6 www. The full migration will simply allow further evolution of the Internet. Of course, more important than the hardware requirements that the implementation of IPv6 will impose, are the training requirements for networking professionals. IPv6 will bring another opportunity for professionals to train and grow. There are many resources available to start learning about IPV6, some of them are listed below. http://www.ipv6forum.com/ |
