Activités autour d’IPv6
IPv6 (Internet Protocol version 6) is a protocol standardized by the IETF (Internet Engineering Task Force) to overcome IPv4 limits. The IPv4 protocol, widely used today, was designed in the 70s and cannot match actual requirements.
The main difference between IPv4 and IPv6 is the length of the address. IPv6 addresses are encoded on 128 bits, making it possible to have an infinite number of devices connected to the Internet. These 128 are composed of 2 different parts:
- The first 64 bits identify the network
- The last 64 bits are the interface indentifier
IPv6 main goal is to overcome the lack of addresses encountered nowadays. IPv6 also add other new features:
- Hierarchical addressing: the aggregation is improved making it possible to reduce the size of the routing tables.
- Autoconfigurations: Workstations can get an address automatically using a stateless address allocation mechanism integrated specified for IPv6.
