Do anyone have knowledge of where to find ip addresses to insert into example OpenCPN settings so real time AIS targets will show up on the screen? Sources can be for example Vessel Traffic Service with leaked ip addresses or private persons transmitting to Marinetraffic. A while ago, an ip address leaked from the Norwegian VTS and with that ip inserted into OpenCPN, all targets along the coast of Norway was displayed on the screen. Of course, the VTS stopped this when they noticed it.
