TCP Port Interrogator v1.0

TCP Port Interrogator is a user-friendly GUI network utility designed to assist you in determining if a range of TCP ports are open or allow for a persistent connection on a remote target. After entering the target IP address you'd like to scan you can optionally specify single ports to scan (comma delimited) and/or input a range of ports to scan (hyphenated). Example: to scan ports 80, 1080 and 400 through 800 you would input '80,1080,400-800' in any order, precedence doesn't matter to the software, and only those ports will be scanned.

For Windows XP, Vista, 7, 8, 10 (32\64-bit)

Fast TCP Port Scanner

TCP Port Interrogator is multi-threaded (up to 256 threads) and offers a quick yet reliable method of scanning a target for open TCP/IP ports. In addition to this, common or well-known ports can optionally be mapped to their respective port service names. For example: TCP port 25 maps to the service Simple Mail Transfer Protocol (SMTP) and would be included in the scan results instead of just the port number itself. This program is compatible with Windows XP - Windows 10 32/64-bit.
