If the ticket you received does not say "U.S. District Court Violation Notice" across the top, then you did not receive a federal ticket. Federal tickets are issued by law enforcement personnel from agencies such as the U.S. Park Police, U.S. Fish & Wildlife, Department of Defense Police, U.S. Coast Guard, U.S. Provost Marshal, Airforce, Marines & Navy Security Forces, U.S. Postal Police, U.S. Customs, U.S. Border Police, and V.A. Police.
