The /96 mask is part of the configuration requirements provided by my hoster. I don't have access to the reason of that particular subnet mask. I just follow the rules ^^ I don't play with the rules, my hoster immediately threatened me to sever the connection of my server in the first message reporting a problem with my IPv6 interface... I had to show them my configuratio nwas OK to get the log details... And now I just asked them to provide me with the details about the meaning of those add/remove everyone here wanna know. Slow and painful process... --- *B. R. * On Thu, Dec 13, 2012 at 6:13 PM, B. R. wrote: > Thanks Philipp, Pascal for your answers. > > I didn't even make the effort to think over the /128.
