Let's go a lil'more 'lower level':

Can you SSH into your Mango? There's a piece of software we can run from the command line called `drill`. It's used to troubleshoot DNS resolution. That this problem is only happening on the Mango is quite something else. I'd like to chk what's going on w/ the Mango's DNS service.

- `opkg update; opkg install drill`
- `drill +short $yourAsusDDNS`

Example:

```auto
root@flint:~# drill +short quad9.net
;; ->>HEADER<<- opcode: QUERY, rcode: NOERROR, id: 46273
