Dover registered the first away win of their Vanarama National League campaign in stunning fashion after winning 5-2 at Eastleigh on Tuesday.
Ricky Miller and Nicky Deverdics both scored twice while substitute Tom Murphy marked his return from injury by getting the other.
The impressive win, Whites' fourth of the year, sees boss Chris Kinnear's side move up four places to 10th.
It was also Whites third consecutive win against the Hampshire side.
Miller opened the scoring with his second goal of the season, and his first since the 3-2 win over Kidderminster at Crabble on August 11, after slotting past goalkeeper Ross Flitney following an impressive run in the 18th minute.
Former Welling man Ross Lafayette headed his side back on level terms in the 30th minute and that's the way it stayed until an explosive start to the second half.
Joe Partington brought Stefan Payne down in the penalty box three minutes after the break and Deverdics did the rest from the spot.
Eastleigh were level two minutes later when Lee Cook curled a 25-yard free-kick over the wall and beyond Mitch Walker.
Dover regained the lead in the 63rd minute after Flitney was sent off after bringing Payne down and Deverdics scored his second penalty of the night.
Murphy, who was making his comeback following a hamstring injury, replaced Payne and just 10 minutes after coming on scored the fourth from a free-kick seven minutes from time.
But Dover saved the best for last when Miller made it five, smashing home a goal of the season contender from 35 yards off the underside of the bar in the 86th minute.
