I really don' t understand.
You supposedly already have the IP's listed (the fact that you likely have two out of three or even three out of three wrong is a side note).
Just §@c#ing run a few WHOIS queries, like here:
18.104.22.168 ->Akamai <- let me doubt that the dll actually phones home to Akamai
22.214.171.124 ->Google <- let me doubt that the dll actually phones home to Google
person: Akira Kato
address: Keio University, Graduate School of Media Design
address: 4-1-1 Hiyoshi, Kohoku, Yokoahama 223-8526
Since the Author of the Library is called George Mamaladze and is German:
allow me to also doubt that the .dll would connect to a domain of a professor at a Japan University:
Then simply try replacing the .dll version shipped with Gamma Control with the one from the official site (that will be v126.96.36.19979 whilst the one in Gamma Control is 188.8.131.52244) and see if the behaviour is the same, then IF it is, review the Source code for version v184.108.40.20679 and re-build it.
There is no need whatsoever to disassemble/decompile anything, and even if there was, it would be essentially your own homework.
