Explicitly querying [`nscd`](https://man7.org/linux/man-pages/man8/nscd.8.html) might come in handy

if your program runs in a container or jail without direct internet access, but you still need to

look up a domain name for some reason.

```rust,ignore

use std::net::{IpAddr, Ipv4Addr, Ipv6Addr};

use nscd_lookup::sync::lookup;

let localhost: Vec = lookup("localhost", &mut Vec::new(), None)

    .expect("should be able to look up addresses")

    .expect("address list should not be empty")

    .collect();

assert!(localhost.contains(&IpAddr::V4(Ipv4Addr::LOCALHOST)));

assert!(localhost.contains(&IpAddr::V6(Ipv6Addr::LOCALHOST)));

```

Or with the feature `"tokio"`:

```rust,ignore

use std::net::{IpAddr, Ipv4Addr, Ipv6Addr};

use nscd_lookup::tokio::lookup;

let localhost: Vec = lookup("localhost", &mut Vec::new(), None)

    .await

    .expect("should be able to look up addresses")

    .expect("address list should not be empty")

    .collect();

assert!(localhost.contains(&IpAddr::V4(Ipv4Addr::LOCALHOST)));

assert!(localhost.contains(&IpAddr::V6(Ipv6Addr::LOCALHOST)));

```

The feature `"reqwest"` enables a resolver that can be used in reqwest clients.
