Enhanced Mode

Unlike browser, most application doesn't support proxy(socks/http). In this case, only system-level transparent proxy is available. There are many optional solutions, Tachyon uses TUN device under the hood.

What Enhanced Mode actually do is create a TUN device, modify system route table and change system DNS(backed up) to tachyon DNS.

Tachyon Service​

The feature is provided by Tachyon Service which is running under root/admin privileges.

On windows/linux, the service will be automatically configured.

On MacOS, you need approve manually in System Settings -> General -> Login Items & Extensions -> App Background Activity -> Tachyon Tray.app.

Tachyon Service will be cleaned automatically after Tachyon uninstalled.

Fake IP​

Once Enhanced Mode is enabled, Tachyon sets the system DNS to its internal DNS server (198.18.0.2).

  • A/AAAA Queries: All address queries are intercepted and resolved to a "Fake IP" within the reserved ranges (IPv4: 198.18.0.0/15, IPv6: fc00::/7). These responses are served with a very short TTL (1s) to ensure the mapping remains dynamic and fresh.
  • Other Query Types: Non-address queries (such as MX, TXT, or CNAME) are forwarded directly to the configured upstream/system DNS.
