    Heh, I just realized this won't help a whole helluva lot because 
www.yahoo.com's round-robin setup isn't contiguous:

    66.94.230.35
             .39
             .41
             .45
             .48
             .49
             .51
             .52

    And neither is www.hotmail.com (which redirects to passport.net anyway:

    207.68.171.233
              .239
              .245


    Do you suppose there are servers on the missing IPs, but they're 
just not operational at the moment?  (Which wouldn't surprise me to be 
honest.)
