Internet protocol Ipv6 is a technology created in the late 1990s, but it has not been implemented in network infrastructures as expected. This paper presents the IPv6 protocol, its advantages and the challenges for its adoption and proposes a mechanism to implement it in an IPv4 environment without losing connectivity with IPv4 and IPv6 networks. Finally, the paper presents a case of implementation in a real IPv4 infrastructure and the tools and configuration applied for its operation.

At this moment is difficult to think in a world without internet, that is why it is important to guarantee the correct and efficient network operation and the easy administration. On the other hand, it is important to use new technologies used by companies such as Google and Facebook that improve the operation of the networks. One of this technologies is Software Defined network-SDN, which allow centralizing the administration of the network and virtualizing its operation. This paper presents the SDN technology, its advantages, implementation mechanisms and a group of application than can be used to create and configure it.
