Tool for checking IP numbers for domains

This is a great tool! You can check multiple URL´s up to 10 at once.
The reason for use this tool in SEO purposes is that you can see at what Class C ip your inlinks for example is located.
A perfect time to use this tool would be if you are offered many links from various domains from the same person.

It is important to have many inlinks from various IP numbers when you are promoting your website, Google seems to devalue if you have all your incoming links from the same class C ip.

Here is a picture on how it looks:

As you can see in this specific image it is obvious that domain nr 5-9 is located at the same IP.

The reason why Google devalues inlinks from the same Class C IP is to avoid webmasters from building huge networks of sites linking to each other I believe.
But of course you are allowed to own and operate a large number of sites, if you are doing just that you might want to consider using various webhosts.
