I have IPv6 enabled for a few months now and have havy abuse from 2001:250::/32 (China Education and Research Network). It is the first abuse from IPv6 for me. So i was wonder what to block?
Most providers in Europe give a /64 or /56 IPv6 subnet to hosting customers and /48 to home users. So blocking such range would be ok to block one customer.
Any ideas or experiences with ipv6 blocking in general?
