The ircDDB-Network is a amateur radio network for exchanging routing information. 

There are several amateur radio systems that are able to reach individual ham radio operators, due to the use of unique callsigns around the world. 

These systems need to be fed with the latest data where ham radio operators are reachable. For example, ICOM introduced the first radios with digital voice (D-Star) on the amateur radio market, 

which are capable of addressing QSO partners directly (call sign routing). The ircDDB-Network provides a solution to distribute the essential routing information across its entire network.
