# libp2p-dns
This crate provides the type `DnsConfig` that allows one to resolve the `/dns4/` and `/dns6/`
components of multiaddresses.
## Usage
In order to use this crate, create a `DnsConfig` with one of its constructors and pass it an
implementation of the `Transport` trait.
Whenever we want to dial an address through the `DnsConfig` and that address contains a
`/dns/`, `/dns4/`, or `/dns6/` component, a DNS resolve will be performed and the component
will be replaced with `/ip4/` and/or `/ip6/` components.
