A MAP to Easier, More Scalable IPv6 Deployments

…re two versions of MAP – translated (MAP-T) and encapsulated (MAP-E). In MAP-E IPv4 traffic is encapsulated into IPv6 using a v6 header before it is sent over the v6 network. At the network operator’s boundary router, the IPv6 header is then stripped, and the IPv4 traffic is forwarded to the v4 Internet. In MAP-T, the IPv4 packet header is mapped to the IPv6 header and back. The difference between the two options is evident in their names. MAP-E…

Tips and Tricks: Nmap is still relevant

…options, UDP, and Nmap Scripts, as that would take too long. But what if I want to run the same scan to my home IPv6 range? It will have a /64 allocated to it, or about 18 quintillion addresses. Let’s compare a sweep of the entire Internet with my home IPv6 range: The Internet: 2^32 = 4,294,967,296 [1] The home range from my ISP: 2^64 = 18,446,744,073,709,551,616 [2] A stark difference! So, how will I scan this? Is that just one network? I am…
