Not a particular device.   Rather to a specific callsign/SSID combo.   Messages 
are one of few types of APRS traffic that can not only pass from RF to the 
Internet through igates, but also pass back out of igates (Internet-to-RF).  
Potentially you can message a station on the other side of the world, IF he is 
near an igate.

[Normally a message won't be "reverse-gated" from the Internet to RF unless the 
station being addressed has been heard recently (typically within the past 
hour) and nearby the igate (typically heard direct or via only 1 digi hop). ]
