[WinForm] .net/c# Speedy IP Open Port Scanner v2.0 Ultimate Version

You can specify the IP segment and port to be scanned, as well as the maximum thread to scan

The larger the number of threads, the faster the scanning, and the higher the requirements for computer configuration and network speed, it is recommended to use the default 100 threads

Changelog:

Added rules for scanning ports, allowing you to set individual ports or port intervals, separated by commas

Optimized a lot of code, fixed some bugs,

This version, which should be the ultimate version, will not be updated in the future! Thank you

The new version scans a single port more than 50% slower than the old version

Another streamlined version has been updated to remove the ability to scan logs How about giving it a try

If you test tonight, please reply to me after the test today

After testing, the speed is still not as fast as the previous first version, and the speed of the third version is not half the speed of my batch scanning proxy, what's going on? The speed of the first edition was what I needed. In addition, there is no need for characters such as IP: port open in the log window to appear, as long as the functions of the software are practical, there is no need to fix those fancy things. There is also the third version of scanning a C segment IP and 8 ports, and it is stuck after scanning less than a third, hehe, why is the software getting lower and lower?

At present, it is found that the scanning speed is much slower than the previous version, scanning 7 ports in a C segment, thread 1000, it actually takes 49 minutes, what is the reason for the speed so much slowdown?

Send me a private message with the IP address of the C segment and the scanned port, and I will test it myself

Your version is already good! If you want to make improvements, I wonder if you can make it multi-IP segments? For example, the two IP segments of New York University were scanned at once:
128.122.0.1  128.122.255.255
216.165.0.1  216.165.255.255
