eWhois, Reverse IP, Adsense, Analytics Lookups

Martin Brinkmann — Sat, 23 Jul 2011 16:52:08 +0000

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.

Who shares your shared hosting?

I host my website on shared hosting. My connection is too slow and unreliable to justify running my own server and I have no need to hire a dedicated server or a VPS. Consequently, many other websites are hosted on the same box as mine and I have often wondered their nature. In addition to curiosity, this could be used to check to see you agree with the ethical stance of your webhost, to check to see if any of the other sites drain resources (thus slowing your site) and to check for any possible security risks.

Every server has an IP address and using specialist websites, a list of domains which point to that IP address can be returned. Several websites do this, and many charge for the service.

If one types in a domain or IP address on myIPneighbors, the site lists other domains that point to that IP. It can be a little unreliable, though, no doubt due to the site’s heavy load.

I have already mentioned that this site does have practical uses. It’s interesting to see how packed your host’s server is, so you can see how good a deal you are getting, and what they are hosting. This could be useful as it’s something hosts rarely reveal but is very important to company’s reputations.

It could also make an interesting tool for doing investigations. Using it, you can see what projects companies are launching if they’re silly enough to put the domain on the same server.

Official Google url Alternatives

Did you know that Google hosts several alternate domain names on their servers that all point to the Google search engine ? Instead of accessing google.com you could use an official Google domain name like 138008.org.ru or msm.byu.edu instead to use the Google search engine.

You might be wondering why someone would want to use a different domain name to search the Internet. As we all know search terms are added to the url of the result page which means that anyone who has access to that data can analyze it and see what you have been searching for.

We have for instance heard of Internet Service Providers who sell this data to companies for marketing purposes. AOL released search results in the past to the public for instance which turned out to be a major privacy invasion for several of its users because it was possible to find out the real name by analyzing the search terms.

The alternate websites do add those search terms as well but it is unlikely that they will be monitored as well. If you want to be on the safe side you could use a proxy server instead and point it to Google.com

Here is the list of alternate official Google.com urls:

http://msm.byu.edu/
http://138008.org.ru/
http://americanlandmarkfence.com/
http://intranet.falmouth.ac.uk/
http://leslein.com/
http://netease.google.com/
http://taakra.com/
http://fd2k.dyndns.org/
http://aim.playlinc.com/
http://0038.za.net
http://cpl.playlinc.com
http://gamedaily.playlinc.com/
http://go.ogle.org/
http://googleffffffff8f01a7ed.sbi2testsite1.com/
http://lunaticus.dnip.net/
http://verizon.playlinc.com
http://yvonneschroeder.com
http://zapchu.ppntop50.com/

Here are Google Groups Alternative urls:

http://groups.secureearn.com/
http://groups.lanostrafamiglia.org/
groups.dz18.com

You might be wondering how you can check that these urls are indeed hosted on a Google server. I used a tool called Reverse IP DNS Domain Check Tool from Seo logs for it. Just enter an url or IP and the tool displays all other domains that are hosted on the same server.
