What is Bulletproof hosting?

Definition

Bulletproof hosting describes a provider that claims to ignore all abuse complaints and law enforcement, including for criminal activity. It is distinct from anonymous hosting, which simply does not collect identity data. Bulletproof providers' address space is blocklisted wholesale, so mail is rejected and users face constant CAPTCHAs.

Why Bulletproof hosting matters

It is distinct from anonymous hosting, which simply does not collect identity data. Bulletproof providers' address space is blocklisted wholesale, so mail is rejected and users face constant CAPTCHAs.

Bulletproof hosting in practice

Running a bulletproof server means expecting wholesale blocklisting. Your IPv4 gets flagged, mail bounces, and users hit CAPTCHAs. You would test deliverability, watch abuse queues, and weigh the price: no legitimate mailing, no clean reputation. If you get it wrong, you operate on an island, cut off from normal internet services.

What people get wrong about Bulletproof hosting

People assume bulletproof hosting ignores abuse complaints, so it suits any sensitive project. Correction: it is for criminal tolerance, not privacy. Anonymous hosting simply omits identity data, while bulletproof providers are blocklisted, harming mail and browsing. Choose anonymous, not bulletproof, for legal privacy.
