Only one part of DOMA was declared unconstitutional, that's the part where the federal government was not allowed to recognize same sex unions even if the states recognized those unions. The opinion tosses the "am I married?" issue squarely in the laps of the states.

Surviving is a part which says that states don't have to honor marriages contracted in other states, so whether a statute like that can survive the equal protection/privileges and immunities clauses is a fight for another day.
