function setServers
Usage in Deno
```typescript import { setServers } from "node:node__dns.d.ts"; ```
setServers(servers: readonly string[]): void
Sets the IP address and port of servers to be used when performing DNS
resolution. The `servers` argument is an array of [RFC 5952](https://tools.ietf.org/html/rfc5952#section-6) formatted
addresses. If the port is the IANA default DNS port (53) it can be omitted.
```js
dns.setServers([
'4.4.4.4',
'[2001:4860:4860::8888]',
'4.4.4.4:1053',
'[2001:4860:4860::8888]:1053',
]);
```
An error will be thrown if an invalid address is provided.
The `dns.setServers()` method must not be called while a DNS query is in
progress.
The [setServers](../.././node__dns.d.ts/~/setServers) method affects only [resolve](../.././node__dns.d.ts/~/resolve), `dns.resolve*()` and [reverse](../.././node__dns.d.ts/~/reverse) (and specifically _not_ [lookup](../.././node__dns.d.ts/~/lookup)).
This method works much like [resolve.conf](https://man7.org/linux/man-pages/man5/resolv.conf.5.html).
That is, if attempting to resolve with the first server provided results in a `NOTFOUND` error, the `resolve()` method will _not_ attempt to resolve with
subsequent servers provided. Fallback DNS servers will only be used if the
earlier ones time out or result in some other error.
