about a particular host. This tool is very much helpful in
finding the addresses, phone number etc.

10. Conclusion
One of the main aim of these research is to make
others understand that, there are so many tools
through which a hacker can get into a system. Its
various perspectives.
Student
A student should understand that no software is
made with zero Vulnerability. So while they are
studying they should study the various possibilities
and should study how to prevent that because they
are the professionals of tomorrow
