Most online players use the free LAC Server to find and interconnect with other online players in LAC's online, multi-player missions. For the past several years, the official LAC server has been operating at IP address 192.34.59.172, and LAC is configured to access it by default.

LAC's official server is available free of charge, and the free source code is published here:

https://sourceforge.net/projects/lacserver/

So the day may come when there are multiple instances of unofficial LAC servers available for more widespread use. Users desiring to take advantage of one of these additional, unofficial LAC servers will be able to edit their LacConfig.txt file to specify the IP address that corresponds with the alternative LAC server.

However, it the LAC server is ever abandoned or otherwise becomes completely unavailable and if there are no unofficial alternatives, LAC players can still use the single "Head To Head" mission to fly with another person over the Internet.

That "Head To Head" mission has been enhanced in early 2026, and you can learn a lot more about it in this discussion from our "Wish List" forum:
