IPv6 and forensic requests

Sun Feb 10 15:28:17 UTC 2019

Hello Jordi,

thank you, I will take a look on Jool!

Exactly CLAT was the issue.

First, I thought to provide a /128 to every mobile, and then do a static 
6to4 to certain public IPv4. But it seems mobile need a /64, and it uses 
a lot of random IPv6 inside assigned /64, several addresses together at 
each time, CLAT uses the most of it (on Android). So direct translation 
6->public4 is impossible.
