SNI Finder

This script will scan all domains with TLS 1.3 and h2 enabled on your VPS IP address range. These domains are useful for SNI domain names in various configurations and tests.

When you begin the scan, two files are created: results.txt contains the output log, while domains.txt only contains the domain names.

It is recommended to run this scanner locally (with your residential internet). It may cause VPS to be flagged if you run a scanner in the cloud.
