I do not fully get how the Intergalactic Research Network works. Can someone help.
Thanks,

The IGN links the research facilities of different planet. Build Level 1 IGN and the two highest level research labs are linked. Level 2 then the three highest Research Labs are linked.

IGN dramatically reduced tech build times.
