//! This module exports a DNS resolver, which is also the default resolver used in the
//! [`crate::Endpoint`] if no custom resolver is configured.
//!
//! The resolver provides methods to resolve domain names to ipv4 and ipv6 addresses,
//! and to resolve node ids to node addresses.
//!
//! See the [`node_info`](crate::node_info) module documentation for details on how
//! iroh node records are structured.
