188.8.131.52, this ip has been flagged by 8 vendors as malicious, I get varying
responses for what it is used for (an os updater or a file distributer) and
wanted to ask what does Cygwin use it for? I can't seem to contact it with

Cygwin has thousands of packages with many executables in each, plus thousands
of libraries which may have many DLLs, all developed or packaged by volunteers.
Did you get the application from the cygwin.com site, or install it using the
installer downloaded from the site home page URL, accessing an official Cygwin
Any other process is entirely at your own risk and may contain malware!
It is extremely unlikely any Cygwin package attampted to access any MS address
or resources, as the newlib libc is BSD or compatible licensed, and Cygwin is
GPL or compatible licensed, so packages have to be limited in what they are
allowed to do on networks during install.
Your company may have filters intercepting library and system DLLs, and much
else on the internet, and may proxy cache downloads, which could interfere with
anything else you do.
It would be advisable to ask your network security folks about such anomalous
