Google recently filed for a patent on their algorithm, which means a large part of the components of it have become public.
You can find the document here:

But a particular part that's important to me is this:
"Google’s patent references specific types of ‘information relating to how a document is hosted within a computer network’ that can directly influence the ranking of a specific web site.
This is Google's way of determining the legitimacy of your domain name.
Therefore, the credibility of your host has never been more important to ranking well in Google’s SERP’s.
Google states they may check the information of a name server in multiple ways.
Bad name servers might host known spam sites, adult and/or doorway domains. If you’re hosted on a known bad name server your rankings will undoubtedly suffer… if you’re not blacklisted entirely.
What I found particularly interesting is the criteria that Google may consider in determining the value of a domain or identifying it as a spam domain; According to their patent, Google may now record the following information:
• The length of the domain registration… is it greater than one year or less than one year?
• The address of the web site owner. Possibly for returning higher relevancy local search results and attaching accountability to the domain.
• The admin and the technical contact info. This info is often changed several times or completely falsified on spam domains; again this check is for consistency!
• The stability of your host and their IP range… is your IP range associated with spam?
• Securing a reputable host can and will go a long way in promoting your web site to Google.
Google’s rationale for domain registration is based on the premise that valuable domains are often secured many years in advance while domains used for spam are rarely secured for more than a year.
If in doubt about a host’s integrity I recommend checking their mail server at

So we ought to be careful when we choose a host especially when we're being lured by cheap web hosting. All of your SEO efforts could be out the window if you've got a host that is less than reputable or just doesn't care about your long-term survivability.
