dns.setDefaultResultOrder

function setDefaultResultOrder(

order: 'ipv4first' | 'ipv6first' | 'verbatim'

): void;

Set the default value of order in lookup and dnsPromises.lookup(). The value could be:

ipv4first: sets default order to ipv4first.
ipv6first: sets default order to ipv6first.
verbatim: sets default order to verbatim.

The default is verbatim and setDefaultResultOrder have higher priority than --dns-result-order. When using worker threads, setDefaultResultOrder from the main thread won't affect the default dns orders in workers.

@param order

must be 'ipv4first', 'ipv6first' or 'verbatim'.
