In this talk we will explore and present various IPv6 scanning techniques that allow attackers to peek into IPv6 networks. With the already known difference between IPv4 and IPv6 firewalling (the latter is worse... ) we then demonstrate how these techniques can be combined and used to obtain a large-scale view on the state of IPv6 in infrastructures and data centers. To give the whole issue a somewhat more fun dimension, we will also look at some (security) sensitive applications of this technique. Complimentary code-snippets will be provided.
