How do I contact the owner of a website? How popular is my site on Digg or Delicious? What other websites are hosted on my web server ? Is my competitor using WordPress or Drupal? xyz.com is loading fast, what is the name of their web hosting company ? Is my blog accessible from China or Japan ?
If you got questions like these in your mind, here are some of the most useful online tools to help you know each and every detail of any website on the planet.
Just-Ping.com - Just Ping help you know whether your website or blog is accessible from different cities of the world. Unlike other online ping services that run from one location, Just-Ping.com runs the ping command on your website from 26 different locations spread across the globe so you have a better idea about your site availability in different regions.
They even have a checkpoint in Shanghai so you can easily find out if some particular website is blocked in China or not.
WhoIsTheOwner.net – If you like to know the contact address, email and phone number of the website owner, this free service will help.
The problem with most whois services on the web is that they are tied to particular domain registrars. So if a website is registered with Network Solutions, you cannot find the ownership details of that site by doing a whois query on say Tucows or GoDaddy.
WhoIsTheOwner is different because it queries the whois database of all popular domain registrars. Extremely useful when sites steal your content and you want to send a warning email to the owner.
YouGetSignal.com - The web server that is hosting your website may also be housing dozens of other websites. YouGetSignal does a Reverse IP Check and lets you know about other websites that are hosted on the same web server as your site.
This is useful information because sometimes one bad site can impact all the neighbours. You may then request your web hosting company to move your site to a different web server.
Trivia: These alternate Google domains were determined with the help of YouGetSignal.com.
WhoIsHostingThis.com – Enter the URL of any website and this online service will show you the name of the company that’s hosting the website.
You need contact information of the web hosting provider for writing a DMCA Notice or if you are looking to switch web hosts.
Type the web address of any web page and Social meter will show you the exact number of times that page has been digged, bookmarked or saved on various social websites.
