Summary5775: Review behaviour of brute force logins with IP address
DescriptionThe current behaviour with failed logins is that brute force compares to exact IP address.

Is this secure enough? Perhaps we should compare to the first three(six) parts instead so it is more tolerant of botnets trying to target a specific user account. Or, do away with IP checking completely.
Additional InformationThe current set-up allows an army of botnets on different IP addresses (especially IPv6) to mass-attempt logging in to a user's account. While still very difficult to do if the user has a good password and brute force security is strong (likely to run out of IPs from brute force banning before a success happens), I think we can do better than comparing full IP address on every attempt.

Comparing the first three octets won't help much, especially not with botnets. Making it too broad risks locking users out of their own accounts. Just comparing one IP address is still useful because it is still very possible a lone individual may try and get in just on their own machine.
