Protect and IPv6

Hi JetPack,

I am using the Protect tool to protect my site against brute force attacks. While this seems to be a good choice in general, I am struggling with the additional maths exercises when logging in from an IPv6 connection. Since I have IPv6 at home as well as at work, I always get this and it is annoying.

I suppose that you are using some blacklists for IPv4 addresses to protect against brute-force attacks? Can you do the same for IPv6? Or maybe blacklist the whole /64 or /56 when brute-force attacks are detected? Or display the additional math only after one unsuccessful attempt?

Thanks and regards,
Johannes
