Only a few AIS receivers or serial-to-ethernet converters are able to send your data to multiple destinations. Most of them are not capable of doing so.
However, if you are already using your own equipment, we can do it for you. If you wish to be forwarding your raw AIS data feed to one of your own systems or to share the data with other vessel-tracking services also (apart from MarineTraffic), we could forward your data to any of your requested destination(s). All we need is the destination's IP address, port number and protocol (TCP or UDP).
Simple as that!
