    Resolves a hostname (e.g. 'nodejs.org') into the first found A (IPv4) or AAAA (IPv6) record. options can be an object or integer. If options is not provided, then IPv4 and IPv6 addresses are both valid. If options is an integer, then it must be 4 or 6.

    Alternatively, options can be an object containing these properties:

    • family <Number> - The record family. If present, must be the integer 4 or 6. If not provided, both IP v4 and v6 addresses are accepted.
    • hints: <Number> - If present, it should be one or more of the supported getaddrinfo flags. If hints is not provided, then no flags are passed to getaddrinfo. Multiple flags can be passed through hints by logically ORing their values. See supported getaddrinfo flags for more information on supported flags.
    • all: <Boolean> - When true, the callback returns all resolved addresses in an array, otherwise returns a single address. Defaults to false.

    All properties are optional.
