Jeff0045,
I will not comment that you are correct or incorrect that in fact these 2 companies are connected.
HOWEVER,
the connection itself cannot be proven or disproven because they use the same name server.
An example would be if you hosted a website with my company, your site and my sites would each have the same name servers….but that would not automatically mean our companies were connected except that you would now be a client.
Also, depending on the type of content your site had, would also dictate what IP Address would be assigned to your site.
I have numerous clients that have the same IP Adress, and yet their companies are definately different entities.
The sharing of IP Adresses has been around a long time and allows hosting companies to stack websites on a single IP to cut down the number of “class C” addresses they must purchase.
There are other technical reasons to do this such as load balancing etc….
When looking for connections between company ownership and management, maybe you should look closer at the “Registrant” contact. (legal owner of the domain in ICANN’s eyes)
You can also look at administrative and billing contacts, (most often the same as registrant but sometimes this could be other companies)
The technical contact can sometimes be directly related to the Owner, but in some cases som Web Hosts require that they be listed as a tech contact on the domain so they may manage any dns changes etc…so that if a dns change must be made they can do so without having to wait for responses from the owners and so that the website will not be down during that time.
Sorry to be so lengthy….
Rick
