NAMESERVER07: To check whether authoritative name servers return an upward referral

Test case identifier

NAMESERVER07 To check whether authoritative name servers return an upward referral

Objective

The configuration and/or implementation of some authoritative name servers causes them to return an upward referral to the root zone. There are proofs that such a behaviour could be used for DDoS attacks

Inputs

The domain name to be tested.

Ordered description of steps to be taken to execute the test case

If the input domain to be tested is the root, exit from the test.
Retrieve all address records for all the name servers using Method 4 and Method 5.
An NS query is sent to each name server IP address found in step 2, with the root “.” as the destination
If any of the query returns with one or more responses in the authority section, then this test case fails.

Outcome(s)

The test case is Ok only if there are no responses in the authority section

Special procedural requirements

None.
