Does .ip exist?
No. No — .ip is not a TLD. An IP address is the number a domain points to, not an extension.
The full story
IP (Internet Protocol) addresses are the numeric destinations domains resolve to — the thing DNS translates a name into. '.ip' looks TLD-shaped to network folks, but it has never been delegated to the root and ICANN holds no application for it. If you're building networking or infrastructure tooling and want that flavour, the endings below are real and available.
