Authorized testing only. Practice on systems you own, isolated labs, or targets with written permission. Unauthorized access is illegal.

When

How

Find your public IP; search Shodan/Censys; close unexpected ports at the router.

Why

External view is the truth for home exposure.

shodan host YOUR.PUBLIC.IP
