Google IP Usability detection script implemented by Python _python

Python 3.4+ is required, and a parameter is used to select a test search service or a GAE service. Testing GAE services requires modifying the first two variables. Read the IP address or IP segment (like 192.168.0.0/16) list from standard input, one per line. Available IP output to standard output. Real-time test results output to standard error. 50 thread concurrency.
