testing dns servers

[Zhihao <zhihao () root sg>]

Hi,

How would you guys test a dns server for holes?

Here are some that i thought of..

1. Make sure it does not allow recursive queries.
2. Make sure it does not allow zone transfers from unauthorized hosts.
3. Make sure it is not vulnerable to dns cache poisoning.

Anything other vectors we could look at?

Cheers.
