Root-Me reachable over IPv6

Root-Me made a big step forward and has now one foot in the IPv4 world and an other in the IPv6 hot and shiny one. The other good news is that you don’t have to do anything: it should just work with or without IPv6 support on your side.

Very few but some challenges remain IPv4 only though. The CTF AllTheDay architecture is ready for IPv6, but most of the CTF Virtual Machines are not and until we fix them, CTF will continue to be an IPv4 only thing (hopefully it won’t stay so for to long).

A big thanks to the team and especially to spump for the work behind this !
