`dns.resolveAny` and `dns.resolve` with `"ANY"` has the similar behavior like `$ dig <domain> any` and returns an array with several types of records. `dns.resolveAny` parses the result packet by several rules in turn. Supported types: * A * AAAA * CNAME * MX * NAPTR * NS * PTR * SOA * SRV * TXT Fixes: https://github.com/nodejs/node/issues/2848 PR-URL: https://github.com/nodejs/node/pull/13137 Reviewed-By: Anna Henningsen <anna@addaleax.net> Reviewed-By: James M Snell <jasnell@gmail.com> Reviewed-By: Roman Reiss <me@silverwind.io>v6
