The dot before "invalid" indicates that "invalid" is a TLD. See also section 2 of RFC 2606. BTW, 3GPP TS 29.231 (http://3gpp.org/ftp/Specs/html-info/29231.htm) describes the same for unspecified connection address. So create whatever domain name you like within ".invalid" TLD. I think "x.invalid" is a reasonably short one.

Why have we put a leading "." on "invalid"? We do not write, e.g., ".bell-labs.com". I know of no other place where a domain name is written with a leading period.
