Description

A very fast asynchronous TCP port scanner that sends SYN packets at high rates and can scan large address ranges quickly.

It is network security tooling for administrators. Use it only on networks you own or are authorized to test, because high-speed scanning can disrupt systems or violate policy.

How to run
