A relative of a missing passenger cries at a vigil in Beijing on April 8, 2014. Australian Defense Force divers scan the water for debris in the southern Indian Ocean on April 7, 2014. A towed pinger locator is readied to be deployed off the deck of the Australian vessel Ocean Shield on April 7, 2014.
From what I've learned in a similar search, I believe the DPO is the abbreviation for Discontinued Post Office. The AE definitely designates Army Europe and the 09498 part of your query would be the APO zip code for a former military installation.
APO stands for Army Post Office, and is associated with Army or Air Force installations. FPO stands for Fleet Post Office, and is associated with Navy installations and ships. I don't know what the actual letters stand for, but anyone with that type of address is in the military and stationed overseas.
