How much is an acceptable standard to the community? Individual /32s ( or /64s)? Some tipping point where 50% of a /24 (or whatever it's IPv6 equivalent would be) has made your naughty list that you block the whole prefix?
My gauge is volume of obnoxious traffic. When I get lots of SSH probes from a /32, I block the /32. When I get lots of SSH probes across a range of a /24, I block the /24.
Do you people have nothing better to do than scan firewall log files and insert rules to block stuff that was already blocked by default? Hint: if ssh probes spams your log then move your ssh service to a non standard port. Regards, Baldur
