Most self hosted blogs and websites are on shared IP hosting. This means that you are sharing an IP address or one machine with several other sites. If you would like to check you IP neighbors there are online tools which will allow you to do that.
AbouThiSite is one of those web services which give you information about a website. It will give you the usual general information like IP address, owner, daily visitors, pagerank and language used. AbouThiSite will also give you information about where the site is hosted and the location of the host including the country and city of the server. It even displays the longitude and latitude of the server the website is installed along with a map. It is totally unnecessary but it’s still good to know. The service can also be used to check if a website does not comply with W3C standards.
AbouThiSite displays in list the domains which are hosted with the website that you are checking out. You can see the list on the lower left corner of the page. On the right side will be a form in which you can preview the IP neighbors of the website.
