Modern web security isn’t just about blocking obvious spam and attacks. Many threats today come from servers and automated tools hosted on commercial hosting providers, cloud services, or data centers – rather than from ordinary end-user devices. BotBlocker includes a system for Hosting Detection, and this data is a powerful tool for improving security. Understanding where your traffic really comes from gives you a real advantage when it comes to protecting your site from automated abuse.
Hosting Detection means analyzing the IP address of each visitor and checking whether it belongs to a range used by a data center, cloud service (like AWS, DigitalOcean, Hetzner), or a web hosting provider. This is different from traffic coming from residential ISPs, mobile networks, or corporate VPNs.
BotBlocker uses up-to-date lists of hosting ASNs (Autonomous System Numbers) and IP ranges to quickly identify traffic that originates from such infrastructure. These lists are regularly updated to keep up with new providers and changes in IP allocations across the internet.
According to Imperva’s Bad Bot Report, a significant share of bad bot traffic originates from data center IP ranges. This confirms that Hosting Detection is not just a theoretical feature but a practical filter that addresses one of the most common real-world attack vectors.
The combination of Hosting Detection with other signals makes the system much more accurate. A single signal alone can produce false positives, but when hosting origin is combined with missing browser fingerprints or unusual request patterns, the confidence level rises sharply. This layered approach is what separates smart bot filtering from simple blocklists.
Contact forms, comment sections, and API endpoints are frequent targets for automated abuse. When Hosting Detection identifies that a request comes from a known data center range, BotBlocker can silently apply a challenge or simply reject the request before it reaches your application logic. This keeps your database clean and reduces the cost of processing junk submissions.
For e-commerce sites, this matters even more. Credential stuffing attacks, fake account creation, and price scraping are almost always carried out from hosting infrastructure. Applying Hosting Detection at the entry point stops a large portion of this activity without touching real customers.
Bot traffic from hosting providers inflates your page view numbers and distorts conversion metrics. When you use Hosting Detection to filter out this traffic from your analytics, you get a clearer picture of how real users interact with your site. This helps you make better decisions about content, marketing, and user experience. Tools like Google’s crawler documentation make a clear distinction between verified crawlers and unverified bots – which reinforces why knowing the origin of traffic matters.
Can real users come from hosting providers?
Rarely. In 99% of cases, it’s bots, automated scripts, or developers/testers. Exceptions are possible (for example, someone using a cloud-based VPN), but they are very rare for most sites.
Does BotBlocker automatically block all hosting traffic?
No, Hosting Detection identifies and flags it. Blocking or additional filtering is up to your settings and combination with other signals.
Does this slow down my site?
No, detection is fast and optimized for high-traffic environments.
How often are the hosting IP lists updated?
BotBlocker maintains regularly refreshed ASN and IP range databases to make sure Hosting Detection stays accurate as providers grow and change their allocations.
