IPRegion — determines your IP geolocation using various GeoIP services and popular websites

Options:
  -h, --help           Show this help message and exit
  -v, --verbose        Enable verbose logging
  -d, --debug          Enable full debug trace and save full trace to file and upload it to 0x0.st
  -j, --json           Output results in JSON format
  -g, --group GROUP    Run only one group: 'primary', 'custom', 'cdn', or 'all' (default: all)
  -t, --timeout SEC    Set curl request timeout in seconds (default: $CURL_TIMEOUT)
  -4, --ipv4           Test only IPv4
  -6, --ipv6           Test only IPv6
  -p, --proxy ADDR     Use SOCKS5 proxy (format: host:port)
  -i, --interface IF   Use specified network interface (e.g. eth1)

Examples:
  $SCRIPT_NAME                       # Check all services with default settings
  $SCRIPT_NAME -g primary            # Check only GeoIP services
  $SCRIPT_NAME -g custom             # Check only popular websites
  $SCRIPT_NAME -g cdn                # Check only CDN endpoints
  $SCRIPT_NAME -4                    # Test only IPv4
  $SCRIPT_NAME -6                    # Test only IPv6
  $SCRIPT_NAME -p 127.0.0.1:1080     # Use SOCKS5 proxy
  $SCRIPT_NAME -i eth1               # Use network interface eth1
  $SCRIPT_NAME -j                    # Output result as JSON
  $SCRIPT_NAME -v                    # Enable verbose logging
  $SCRIPT_NAME -d                    # Enable debug and save full trace to file and upload it to 0x0.st
