Perform Web-based network queries with these sites

When you want to perform network queries for troubleshooting or data collecting purposes, the standard approach has been to launch a non-graphical command line interface (CLI) in Windows or a shell prompt (such as Bash) in Linux to display the input and output of the commands you use. While this practice is undoubtedly quick and lightweight, the functionality of many networking commands has been replicated on dozens of websites which allow network administrators the same capabilities in graphical, web-based environments.

Nearly all of the networking-related command utilities have been listed and described in this blog. Some of these commands include netstat, nslookup, ping, traceroute, and whois among others. This post will show you the best and most popular websites for using these types of commands in browser-based graphical user interfaces (GUIs). These websites will be listed in alphabetical order based on domain name.

Tagged with , , , , , , Web proxy is a free web proxy that lets you anonymously visit websites. Each time you normally surf the web, you share some details about your computer and Internet connection, such as your browser version, IP address, and Internet service provider (ISP) name. Some web portals and search engines like Google even store a record of your IP address and Web searches.

Web proxies like Anonymouse act as intermediaries between your computer and the websites you visit by passing along HTTP (web) protocol requests and displaying the contents of the requested URL within your browser. For example, if you use Anonymouse to visit Google and you start some keyword searches, Google will only see Anonymouse as its visitor, not you. Any data that Google sends to Anonymouse will then be forwarded by Anonymouse to you.

To take online privacy to the next level, have a look at the Tor anonymity tool.
