DNSR-631 — Answer resource record has unimplemented or incorrect type
Resource record (RR) of printed type and order contain unexpected type (printed in the parenthesis).
For ANSWER RRs it means unimplemented type.
For NMSERV and ADDREC RRs it should mean either unimplemented or incorrect type. In the case of CNAME RRs within NMSERV (Authority) section, the default reaction is A-level. It should be changed to the W-level by the REQUEST-ACL.IGNORE-VOID-RR item.
Whole answer is ignored (and next server is tried) in case of E and A-level, record is ignored in case of W-level.
