Does .invalid exist?

Not really. No — .invalid is reserved to be, well, invalid. It's guaranteed to never resolve.

The full story

RFC 6761 reserves .invalid for cases where software needs a domain that is certain to fail DNS resolution. It's the only TLD whose entire job is not existing.

Wondering about another extension? Every real TLD is in the directory.
