Synthetic SOA returned by BIG-IP has the MNAME and RNAME fields reversed, resulting in the wrong values being noted as the primary name server and mailbox of administrator, respectively.
Per RFC (rfc1035) the order of the fields is significant and MNAME must come before RNAME. When reversed, consumers of the synthetic SOA will associate the wrong values with the wrong fields.
-- Set the failure-rcode-response enabled and failure-rcode-ttl on a down WIP. -- Perform a DNS query. -- Observe the SOA.
