SYNTAX05: Misuse of '@' character in the SOA RNAME field

Test case identifier

SYNTAX05 There must be no misused '@' character in the SOA RNAME field

Objective

The SOA RNAME field does not allow the '@' characters to be used for describing a mailbox. The first dot ('.') is thus translated into the '@' character. This is a common mistake. The rules are defined in RFC 1035.

Inputs

The domain name to be tested.

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

  1. Obtain a set of name server IP addresses using Method4 and Method5.
  2. Create a SOA query for the zone.
  3. Send the SOA query over UDP to each name server IP address until a response is received or until the set is exhausted.
  4. Check if the RNAME field contains a '@' character.

Outcome(s)

If there is any '@' character in any SOA/RNAME field, this test case fails.

Special procedural requirements

None.

Intercase dependencies

The de-escaped output from this test is used by SYNTAX08.
