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.
