After landing in ZZZ; Aircraft X; while parked waiting for a gate; the aft FA (Flight Attendant) called the cockpit stating that during final descend around 6;000 ft. they smelled the dirty sock odor in the back of the airplane; the odor was present then went away during the final descent and the upon landing the odor came back and went away again. I told her that we were going to park; disembark and have Maintenance inspect the airplane. We parked shortly after and disembarked the passengers. I talked to the Flight Attendant number 1 and asked him about it and he told me that he went back and did not smell anything. I also asked him if the other [cabin] crew members were OK and he replied yes we all are OK. The odor was spontaneous and went away. I call Maintenance in ZZZ1 and reported the issue and made a log book entry. Maintenance ZZZ1 told me they will address the issue with maintenance in ZZZ.No further actions was required and all crew members went to the hotel and worked the next flight the next day without any complaints.
Air Carrier Captain reported aft cabin Flight Attendant notified the flight deck of an intermittent 'dirty socks' odor from final descent until parked.
