  We propose a regular classical field theory realisation of the
Dvali-Gabadadze-Porrati mechanism by considering our universe to be the
four-dimensional core of a seven dimensional 't Hooft-Polyakov hypermonopole.
We show the existence of metastable gravitons trapped in the core. Their mass
spectrum is discrete, positive definite, and computed for various values of the
field coupling constants: the resulting Newton gravity law is seven-dimensional
at small and large distances but can be made four-dimensional on intermediate
length scales. There is no need of a cosmological constant in the bulk, the
spacetime is asymptotically flat and of infinite volume in the
extra-dimensions. Confinement is achieved through the local positive curvature
of the extra-dimensions induced by the monopole-forming fields and for natural
values of the coupling constants of order unity.
