Not much point in hashing a (v4) IP, there's 4 billion of them, trivial to undo (you won't be able to change the salt)
There's nothing wrong with storing individual IPs temporarily for security and functionality purposes, but you're still collecting them - if nothing else they'll show up in your netflow sessions and your netstat output

Here is my IP as a sha256, please reverse it and show me you actually know what you're talking about: 20adfe5288d85b6279dc65eff126828c0b20b896cb853caef9de0d6251e46169
- iso1210 6y agoTo do that I'd have to calculate 4 billion sha256 hashes. This quote is from 2012: "I do 622 million SHA-256's per sec on a Radeon HD5830." You might have salted it or encoded in a 'clever' way like hex or words or whatever, but as you know the method you can do it.
