IP Address Blocked Error Block for React

Pressing it with an empty organisation or a reason that says nothing names each problem under its field and focuses the first. Otherwise the button waits under a second, and the form is replaced, in the same space, by what was recorded: "Review requested", a reference and the organisation, with Edit request to go back. Nothing is sent. To wire it for real, post the two fields and the address to your abuse desk where the code says so, and show the reference your system gives back.

From the typed attempts: the rule says five failures in ten minutes block an address, so the block lifts when the oldest attempt (14:22:05) is ten minutes old and only four remain in the window. The page adds the window to the first time and prints the minute, so the text and the data can't disagree. If your rule is a fixed cooldown, replace UNBLOCKS with the time your system stored.

No. It is in 203.0.113.0/24, a range reserved for documentation (RFC 5737), so it can never belong to a real visitor. In your app show the visitor's own address, and be careful with what else you show: the five attempts here list the accounts that were tried, which is fine for the person who made them, but not for a stranger behind a shared address.

Because on a phone the way forward has to be on the first screen: the heading says what happened, the form follows, and the evidence (the long part) comes after it. On a wide screen the form is at the start of the card and the evidence at the end, in the same order a keyboard or a screen reader meets them.

No: a component can't. Send the real HTTP status from your server or edge, so clients, monitors and crawlers see a 403 (or a 429 for a pure rate limit) and not a 200 with an error drawn on it.

Yes: it writes the address to the clipboard and a polite status line says "Copied 203.0.113.42." If the browser refuses, the line says so and asks you to select the address by hand.
