Print stack traces for process warnings (including deprecations).

### `--dns-result-order=order`
|
||||
|
||||
Set the default value of the `verbatim` parameter in the Node.js [`dns.lookup()`](https://nodejs.org/api/dns.html#dnslookuphostname-options-callback) and [`dnsPromises.lookup()`](https://nodejs.org/api/dns.html#dnspromiseslookuphostname-options) functions. The value could be:
|
||||
|
||||
* `ipv4first`: sets default `verbatim` `false`.
|
||||
* `verbatim`: sets default `verbatim` `true`.
|
||||
|
||||
The default is `verbatim` and `dns.setDefaultResultOrder()` have higher priority than `--dns-result-order`.
