What is a .b16 file?
A .b16 file is a plain text file used by the BitTorrent client to store a list of IP addresses that are known to be malicious or unreliable. This list, often referred to as a 'blocklist' or 'tracker blocklist', helps to prevent your BitTorrent client from connecting to potentially harmful servers or peers. By maintaining this list, users can enhance their security and improve the overall stability of their BitTorrent downloads. The format is simple and human-readable, making it easy to manage and update manually if needed.
