  The mass spectroscopy of exotic meson states is scrutinized in the AdS/QCD
paradigm. The differential configurational entropy is then used to study,
derive, and analyze the mass spectrum of excited exotic vector meson
resonances, whose configurational stability is also addressed. For it, the
hadronic molecule, the hadrocharmonium, and the hybrid description of
heavy-quark exotic mesonic states are employed to more precisely match
experimental data in the Particle Data Group and also to predict the next
generations of heavy-quark QCD exotica in the $Z_c$, $Y$, $\pi_1$, and $Z_b$
exotic meson families.
