all jokes aside, 1918 allows for use of 1918 space in a private network or a 'private internet [sic]' comprised of any such number of private networks as agree to interconnect and cooperate in routing traffic sourced from and destined to said space. it follows that any 1918-sourced traffic you send me is illegitimate. ...
