# Virtual Host Enumeration
Discover hidden virtual hosts on IP addresses by fuzzing the `Host` header. Many servers only respond to specific domain names and remain invisible to standard subdomain enumeration. VHOST fuzzing exposes internal services, development environments, and admin panels that share the same IP but answer to different hostnames.
## When to Use
- You have a list of target IPs from `skill_view(name='origin-ip-discovery')` or `skill_view(name='port-service-discovery')`.
- A server returns default/blank pages for unknown Host headers.
- Subdomain enumeration may have missed internal-only hostnames.
- SSL certificates on an IP list multiple domain names in the SAN field.
- You need to map internal services behind a reverse proxy.
