I've been trying to work out why the PHP `getmxrr()` and `checkdnsrr()` methods do not return successfully for working domains in a number of vagrant VMs that I use.

When looking into this further I tried using simple `dig` commands and I only get an ANSWER for `A` records. Anything else returns nothing.

As an example, here is the 'correct' ANSWER section for an `ANY` enquiry showing all of the records for that exist for an example domain (from an AWS-hosted server). You can see that their are at least `NS`, `TXT`, `A` and `MX` records:

**Debian AWS VM:**

Looking at individual requests on my Vagrant VM though and I get:

```
$ dig reiss.com A

But any other type of record returns nothing:

```

These commands work fine on the AWS server as well as on my Mac OSX host machine locally, it just seems to fail inside my Vagrant/Virtualbox VM.

The problem is also affecting PHP so I don't think it's anything to do with the dig command.

Any ideas?
