About Contabo

Hosting is the one category in our data where the technology is not on the page at all. Contabo is a Hosting business founded in 2003 and trading as Contabo GmbH, selling virtual and dedicated servers well below hyperscaler prices, and a site is attributed to it because of who owns the address it resolves to, not because of anything the site itself declares.

As of October 2026 we place 61,072 sites on its network. Attribution by address range is more reliable than most fingerprinting, since network blocks are registered and public, but it carries an assumption worth stating: the company that owns the address is not necessarily the company that sold the server. Resellers, managed providers and agencies buy capacity in bulk and put their own customers on it, so a share of these sites belong to people who have never heard the provider's name.

Geography shows the effect clearly. France carries 43,167 of the sites, which describes where the data center holding those addresses sits rather than where the customers live. A provider with capacity across Europe, North America and Asia produces a country distribution that is a map of its own infrastructure footprint, and anyone reading the field as customer nationality will be wrong in a way no extra column from us can correct. The suffix that recurs across the base is .com, equally uninformative about nationality and rather more informative about the kind of site being hosted.

What the choice of provider does imply is budget and self reliance. Low cost unmanaged infrastructure gets bought by developers, hosting resellers, small agencies and cost sensitive businesses willing to administer the machine themselves, so the sites on it skew toward self hosted software, custom applications and stacks assembled by hand rather than managed platforms. Anyone selling monitoring, backup, security or managed services is looking at a population that has explicitly declined to pay for those things, which makes the list either a qualified prospect base or a disqualified one depending on the pitch.

The stack detected alongside is where the value concentrates. Knowing which control panels, web servers, content systems and commerce platforms cluster on one provider's ranges tells a software vendor where its installed base actually lives, tells a competing host what a migration would have to support, and tells a security team which of its suppliers share infrastructure. None of that survives a per domain lookup, which returns one address and one owner and no sense of what sits next to it.

The Proprietary nature of the business is a reminder of what the list is not. Nobody sells a customer roster for a hosting company and no directory publishes one. What can be built is the outside view, address range by address range, which is what the file contains and why it is worth having.
