"Binary file ... matches"

[Prinzhorn]

I doubt these ended up in the list on purpose and are the product of grep not having --binary-files=without-match or similar (no idea how you actually generate these files, I just looked into some and saw this by chance)

E.g. Uber

0.em3.dev.uberinternal.com
0.free.dev.uberinternal.com
0search.et.uber.com
Binary file in/python-script-3/output.txt matches <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
a-1.ying.dev.uberinternal.com
a-2.ying.dev.uberinternal.com
a-3.ying.dev.uberinternal.com
a-6.ying.dev.uberinternal.com
a.dc.dev.uberinternal.com
