According to resolv.conf(5) you can by default only configure 3 (!) |
| 14 |
name servers instead of the four you have. |
| 15 |
|
| 16 |
Also, it doesn't make sense to configure a nameserver to return its own |
| 17 |
host name, so I would consider your test case being invalid. |
| 18 |
|

The interesting question would be which name server answers for the case |
| 20 |
that you query some other host name (also since you said what you want |
| 21 |
those servers to do is caching, not authoritative name services). |
| 22 |
|
| 23 |
Since those are public IPs, I happened to positively check for the |
| 24 |
existence of a firewall. Its configuration regarding DNS queries (UDP |
| 25 |
_and_ -- always forgotten -- TCP port 53) would be interesting, esp. |
| 26 |
the configured allowed IP ranges for source and destination. |
