Is there an example domain which is guaranteed not to exist?

Question

I would like to use a domain name in an example. I know that example.com exists for this purpose, but I would like the domain name not to exist (and not to start existing later). Is there any canonical example of a domain name which is guaranteed not to exist?

As per RFC 6761 section 6.4, the domain invalid. and any names falling within .invalid., can be assumed not to exist.
