Recently I came across cool search engine for Cyberspace.
This is the place where you can search by :
- Port Numbers
- Application name and version
- Location - Country and city
- Operating System
- Service name
- IP Address
- CIDR notification - i.e. by IP subnets
This search engine may come in handy while performing external reconnaissance activities.
