Whether you are engaged in development testing or security penetration, you need to do some necessary information collection. Therefore, a port scanner based on Java language development is simply written to meet the requirements.
Currently available features:
* Scan on the Internet * Scan against a target IPv4 * Scan against a target domain * Scan the unique network segments identified by CIDR or IP + subnet mask * Query domain whois informationScan types include: scan a specified port, scan common ports, scan all ports
v 2.0 Features to be added later：
* IPv6 support * Increase system fingerprint recognition * Slow scan and firewall bypass # Install ## Java environment installIf the system has installed the Java runtime environment or Java development kit and the Java version is 8 or above, this step can be skipped. You can check the Java version：
```shell java -version ```If Java is not installed or the Java version is lower than 8, install the Java 8 environment：
Download JDK from Oracle official website:
[JDK download](https://www.oracle.com/java/technologies/downloads/)After downloading the compressed package, unzip it to the folder where you placed the environment, and configure the environment variables, so I won’t go into details here.
