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.

Use whois with DNS query websites

DNS query websites allow you to perform whois searches to find out the following information about other websites:

  • Registrar – the name of the organization (registrar) that registered the domain name. Some DNS registrars are GoDaddy.com and Network Solutions.
  • DNS Servers – the names of the public DNS servers that authoritatively answer DNS queries for the domain names queried.
  • Organizational details – names, addresses, email addresses for the organization that owns the domain name you queried.

For example, a whois search for the domain name cisco.com yields the following results:

Domain Name.......... cisco.com
