It's actually possible to aggregate two, or four, or eight..., adjacent
Class C blocks IF their addresses are aligned, without an internal router.
It is extremely unlikely that they're committed to anything that supports
only classful addressing,
  But
    a) THREE blocks isn't possible, even if they're adjacent, and

    b) because I've run into folks before who imagined they'd heard
somewhere that all 192.x.x.x addresses were private, it never even occurred
to me that this outfit might BE the public allocants of those addresses.  I
doubt if a private enterprise can buy a single whole Class C block any more,
let alone three that are adjacent....
