TCPView - Portable Endpoint Process Monitor

tcpview

TCPView is a lightweight and portable Windows network monitoring tool that provides a comprehensive real time overview of all active TCP and UDP network connections on your system. Developed by Microsoft’s trusted Sysinternals team, it displays detailed connection data along with the exact process names responsible for each network endpoint.

Compared to the built in Windows Netstat utility, TCPView delivers significantly more insight through a clean graphical interface. For command line users, it also includes a console based companion called Tcpvcon, which offers equivalent functionality without a GUI.

IPNetInfo - Retrieve IP Address Information

IPNetInfo

IPNetInfo is a small but powerful free IP address lookup and network information tool that allows users to retrieve detailed information about any IPv4 address. Developed by NirSoft, this lightweight utility functions much like a portable WHOIS lookup tool, making it ideal for network administrators, security researchers, and power users who need fast IP intelligence without relying on online services.

With IPNetInfo, you can quickly view important details such as the IP address owner, country and region, IP range, and available contact information including address, phone, fax, and email (when provided by the registry). Because it runs as a standalone executable, it can be stored and launched directly from a USB flash drive, leaving no installation footprint on the host system.
