## What it is
A Rust + eBPF/XDP tool that drops GFW DNS poisoning packets at the kernel level, allowing clean DNS resolution from 8.8.8.8 without a proxy. It filters poisoned responses by matching packet fingerprints like IP ID, flags, and DNS header markers.

## Use cases
- get uncensored DNS results from 8.8.8.8 without a VPN
- filter GFW DNS poisoning at the kernel level
- resolve blocked domains correctly behind the Great Firewall
- drop DNS hijack packets using eBPF/XDP
- avoid running a userspace proxy just for clean DNS

## When to choose
- you are on Linux with XDP-capable kernel and NIC drivers
- you want a lightweight, high-performance kernel-space DNS poison filter
- you only need clean resolution from 8.8.8.8 and don't need a full proxy

## When to avoid
- you are not on Linux or your kernel/NIC lacks XDP support
- you need general censorship circumvention beyond DNS, such as a full proxy or VPN
- you need a maintained cross-platform solution with active releases

## Facets
- artifact type: cli-tool
