When I research a domain or website, I sometimes want to find out about other websites that the company or owner maintains. Why can this be important? Lets say I want to buy a website about Grand Canyon Helicopter Tours. With a reverse lookup I can make sure that the guy who is selling the domain is not owner of another site in the same niche. This could be bad for numerous reasons and is best to be avoided. A check of other web properties could also provide information about the level of business of a seller, or the expertise.

Ewhois is a free online service that can lookup information about a website online. All you need to do is to enter a url into the form on the service's frontpage. Make sure you only enter the domain name and no protocol in the form. A click on search submits the site to the service, which, after some magic, displays its findings on the results page.

The results page displays general information about the selected domain at the top. You see the domain's IP address, Google Analytics ID, Pagerank, Alexa and Compete Rank as well as the data of the last update. The amount of sites that share the same IP address and Google Analytics ID are also displayed here.


Below that is a tabbed interface that displays the contents of the reverse IP lookup, Reverse Google Analytics ID Lookup, Google Adsense ID Lookup and Whois Record. The Adsense and Analytics tabs are only displayed if the scripts are embedded on the target site.

The reverse IP lookup tab displays all websites that are hosted on the same IP address. Websites with an Alexa rank of less than 1000000 are displayed with their Alexa rank on screen. All others with a link to the website and a link to run the lookup for that site on eWhois.

Both the Reverse Google Adsense and Google Analytics ID lookup list websites that use the very same scripts on their sites. This can be usually tied to the same owner directly. The script may not list all sites of the owner in the listing. Still, the sites listed can reveal useful information about the original site's owner.

Ewhois' service sets itself apart from other services by displaying all the lookups that other services are usually only offering on separate pages. It is easy to use and comes without obtrusive advertising.

      Well it is a bit difficulty to distinguish between name.com domains and files for instance.

    The comments section under this very article (3 comments) is identical to the comments section found under the following article:

    Not sure what the issue is, but have seen this issue under some other articles recently but did not report it back then.

    With the cloud, there is no such thing as unlimited storage or privacy. Stop relying on these tech scums. Purchase your own hardware and develop your own solutions.

      This is a certified reddit cringe moment. Hilarious how the article’s author tries to dress it up like it’s anything more than a png for doing the reddit corporation’s moderation work for free (or for bribes from companies and political groups)

    With Google Chrome, it’s only been 1,500 for some time now.

    Anyone who wants to force me in such a way into buying something that I can get elsewhere for free will certainly never see a single dime from my side. I don’t even know how stupid their marketing department is to impose these limits on users instead of offering a valuable product to the paying faction. But they don’t. Even if you pay, you get something that is also available for free elsewhere.

    The algorithm has also become less and less savvy in terms of e.g. English/German translations. It used to be that the bot could sort of sense what you were trying to say and put it into different colloquialisms, which was even fun because it was like, “I know what you’re trying to say here, how about…” Now it’s in parts too stupid to translate the simplest sentences correctly, and the suggestions it makes are at times as moronic as those made by Google Translations.

    If this is a deep-learning AI that learns from users’ translations and the phrases they choose most often – which, by the way, is a valuable, moneys worthwhile contribution of every free user to this project: They invest their time and texts, thereby providing the necessary data for the AI to do the thing as nicely as they brag about it in the first place – alas, the more unprofessional users discovered the translator, the worse the language of this deep-learning bot has become, the greater the aggregate of linguistically illiterate users has become, and the worse the language of this deep-learning bot has become, as it now learns the drivel of every Tom, Dick and Harry out there, which is why I now get their Mickey Mouse language as suggestions: the inane language of people who can barely spell the alphabet, it seems.

    And as a thank you for our time and effort in helping them and their AI learn, they’ve lowered the limit from what was once 5,000 to now 1,500…? A big “fuck off” from here for that! Not a brass farthing from me for this attitude and behaviour, not in a hundred years.
