In RFC violation yes.


<quote source="rfc2606">
    To safely satisfy these needs, four domain names are reserved as
    listed and described below.

                    .test
                 .example
                 .invalid
               .localhost

       ".test" is recommended for use in testing of current or new DNS
       related code.

       ".example" is recommended for use in documentation or as examples.

       ".invalid" is intended for use in online construction of domain
       names that are sure to be invalid and which it is obvious at a
       glance are invalid.

       The ".localhost" TLD has traditionally been statically defined in
       host DNS implementations as having an A record pointing to the
       loop back IP address and is reserved for such use.  Any other use
       would conflict with widely deployed code which assumes this use.

Rude, no, it's probably someone who thought that /including/ the word "invalid" 
was the way to do it.


Cheers, just my 3 øre,

PS: in the same way, not including "OT" in the subject line here might be 
considered rude. But then, if I were to add it, some newsreader might split the 
thread. So it's difficult to please everyone! :-)
