This module implements a forwarding DNS resolver with two states: +//! * In the `Blocked` state, most queries receive an empty response, but certain captive portal +//! domains receive a spoofed answer. This fools the OS into thinking that it has connectivity. +//! * In the `Forwarding` state, queries are forwarded to a set of configured DNS servers. This +//! lets us use the routing table to determine where to send them, instead of them being forced +//! out on the primary interface (in some cases). use std::{ io, net::{IpAddr, Ipv4Addr, SocketAddr}, |
