Recently, I have discovered a very small tool that could prove useful to some inexperienced computer users. IP Cat is a small tool that determines your IP address and also it is able to change the proxy settings for Internet Explorer.
What is IP Cat?
This is not very spectacular or useful as you can determine your IP address simply by visiting a What Is My IP page, but it also contains a small and useful tutorial about the IP commands like ipconfig, ping, tracert, etc.
Important notice: this tool does not change your IP address. If you want that you need to look for a hide IP tool.
