Usage in Deno
import { type LookupOptions } from "node:dns";
family: number
| "IPv4"
| "IPv6"
| undefined
The record family. Must be 4, 6, or 0. For backward compatibility reasons, 'IPv4' and 'IPv6' are interpreted
as 4 and 6 respectively. The value 0 indicates that either an IPv4 or IPv6 address is returned. If the value 0 is used
with { all: true } (see below), both IPv4 and IPv6 addresses are returned.
hints: number | undefined
One or more supported getaddrinfo flags. Multiple flags may be
passed by bitwise ORing their values.
all: boolean | undefined
When true, the callback returns all resolved addresses in an array. Otherwise, returns a single address.
order: "ipv4first"
| "ipv6first"
| "verbatim"
| undefined
When verbatim, the resolved addresses are return unsorted. When ipv4first, the resolved addresses are sorted
by placing IPv4 addresses before IPv6 addresses. When ipv6first, the resolved addresses are sorted by placing IPv6
addresses before IPv4 addresses. Default value is configurable using
setDefaultResultOrder or --dns-result-order.
verbatim: boolean | undefined
When true, the callback receives IPv4 and IPv6 addresses in the order the DNS resolver returned them. When false, IPv4
addresses are placed before IPv6 addresses. This option will be deprecated in favor of order. When both are specified,
order has higher precedence. New code should only use order. Default value is configurable using setDefaultResultOrder
