Internet DNS Tools

These are my great tools for internet based DNS queries.
The default express option shows you all the information you need as a start. Then you can drill down on the specific options.
This site provides a lot of tools. It also includes the very important check to see if your website is accessible from China and Iran.
The site presents the (Linux) BASH dig command in a web-browser. The following image shows the output and usage of the website.
The site presents a Whois of a domain and provides (a paid) domain history. The following image shows the output of the website.
This site presents you an graphical overview of the structure of the DNS SPF record and shows configuration errors. The following image shows the output of the website.
This site lets you instantly perform a DNS lookup to check a domain names current IP address and DNS record information against multiple name servers located in different parts of the world. This allows you to check the current state of DNS propagation after having made changes to your domains records.
OpenRDAP is a command line client for the Registration Data Access Protocol. RDAP is a replacement for WHOIS, and provides domain name & IP-address registration-information in JSON-format over HTTP.
