I'm getting fed up with running my sites on close to 10 different hosts to get proper diversification of IPs, DNS, etc. I'm looking at using a multi C class IP host (SEO host) and have researched all the top options. But I've found a big issue with all the hosts I've researched and contacted... The IPs they use are registered to just one or a few company names. This means that if you do a WHOIS on the IPs they provide, they'll all show them as being registered to the same or one of a few companies. To me that completely defeats the purpose of this type of service. Why go through the hassle of using different class C, B or even A IPs and have custom nameservers on separate IPs if all someone has to do is a WHOIS and see that all your sites are related? I find it impossible to believe that Google does not currently or won't in the near future take IP registration info into account when detecting link spam or when determining the value of a link between two sites. It's simply too easy for them to do and this is a very powerful way to see through the whole SEO host thing. So, does anyone know of a host offering: Multiple class C IPs Custom nameservers hosted on multiple class C IPs IPs with WHOIS info that is spread across at least 10 different company names? I realize that the logistics for a web host to register blocks of IPs in many different company names is a pain in the ass but that's what you're paying for right? I mean, if not, you've got a huge footprint that defeats the purpose of the service.
