Dark matter is an indispensable component to explain the large scale structure of the universe. However, some theoretical expectations are still in contradiction with observations as, for instance, the large number of predicted satellites, the central mass distribution of galaxies, the presence of massive galaxies and clusters at redshift z > 2. Moreover, LHC data do not indicate detection of supersymmetric particles, posing problems to the nature of dark matter. I will discuss an alternative scenario in which dark matter particles are primordial extreme regular black holes formed at the end of inflation, during the reheating era.
