If anyone cares about the numbers, I've been able to crack my own IP address (85.*) in 10 minutes using john with trivial IP address wordlist generator and plain SHA-512 hash. I suppose you could assume that having salted hashes would mean up to 30 minutes per IP address but that's still not much. I suppose you could use Argon2 or some other crazy hash but... where is this going, really? -- Best regards, Michał Górny
