What Are .onion Sites and How Do They Work?
.onion sites are specialized hidden services on the Tor network, designed to provide users with encrypted and anonymous access to content. These sites utilize the unique top-level domain (TLD) .onion and can only be accessed through the Tor Browser, which ensures privacy and security for both users and site operators1.
The primary distinction between .onion sites and standard domains, such as .com or .net, lies in their accessibility and indexing. Standard domains are indexed by traditional search engines, making them discoverable by anyone using the internet. In contrast, .onion sites are not indexed, meaning they remain hidden from conventional search engines. This lack of visibility is intentional, as it protects user anonymity and the site's content6.
To access .onion sites, you must use the Tor Browser. Other browsers do not support the necessary protocols for connecting to these hidden services. The Tor Browser routes your internet traffic through a series of relays, effectively masking your IP address and encrypting your data, which is essential for accessing these hidden resources securely7.
A .onion address is typically a 56-character string for the current v3 addresses, which are derived from the service's identity public key and include a checksum for verification38. Older v2 addresses (16 characters) are no longer supported, and attempting to access them will result in errors2.
For a practical example, consider testing your Tor Browser connection by visiting DuckDuckGo's .onion site. This verified resource is an excellent starting point for navigating the Tor network and understanding how .onion sites operate2.

How .onion Addresses Are Generated and Why They Change
.onion addresses are generated through a cryptographic process that ensures both uniqueness and security. A v3 .onion address consists of a 56-character string derived from the service's identity public key, a version field, and a checksum, all encoded in base32 format38. This method eliminates the need for traditional domain purchases, enabling operators to create secure hidden services easily2.
Addresses change for several reasons, including service restarts, security updates, or law enforcement actions targeting specific sites9. If a service is restarted or updated, the old address may no longer function, leading to errors such as ‘Onionsite Not Found’2. To find updated addresses, users can rely on dark web directories like The Hidden Wiki, Ahmia, or Torch, which frequently list current .onion sites.
The difference between v2 and v3 addresses is significant. Older v2 addresses are only 16 characters long and are no longer supported on the modern Tor network. Attempting to access these older addresses will typically result in an error message2. In contrast, v3 addresses provide increased security and are designed to enhance the anonymity of both users and site operators through improved cryptographic hashing methods.
For example, a v2 address might look something like ‘abc1234567890def’, whereas a v3 address would resemble ‘abcdefg1234567890hijklmnopqrstuvwxyz123456’. The transition to v3 addresses signifies a move towards greater security and anonymity within the Tor network, making it essential for users to adapt to these changes and ensure they are accessing the correct, up-to-date addresses.
