Internet Freedom Act - Prohibits regulations adopted by the Federal Communications Commission (FCC) in the Report and Order in the matter of preserving the open Internet and broadband industry practices (adopted December 21, 2010) from having any force or effect.

Prohibits the FCC from reissuing such regulations in substantially the same form, or from issuing new regulations that are substantially the same, unless such regulations are specifically authorized by a law enacted after the enactment of this Act.

Exempts from such prohibitions any regulations that the FCC determines are necessary to: (1) prevent damage to U.S. national security, (2) ensure public safety, or (3) assist or facilitate actions taken by a federal or state law enforcement agency.
