## 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](https://datatracker.ietf.org/doc/html/rfc1035).
|
||
|
|
|
||
|
|
### 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](syntax08.md).
