Domain
type Domain = ByteStringSource
Type for domain.
TYPE
Types for resource records.
DNS Error
An enumeration of all possible DNS errors that can occur.
SequenceNumberMismatch | The sequence number of the answer doesn't match our query. This could indicate foul play. |
TimeoutExpired | The request simply timed out. |
UnexpectedRDATA | The answer has the correct sequence number, but returned an unexpected RDATA format. |
IllegalDomain | The domain for query is illegal. |
FormatError | The name server was unable to interpret the query. |
ServerFailure | The name server was unable to process this query due to a problem with the name server. |
NameError | Meaningful only for responses from an authoritative name server, this code signifies that the domain name referenced in the query does not exist. |
NotImplemented | The name server does not support the requested kind of query. |
OperationRefused | The name server refuses to perform the specified operation for policy reasons. For example, a name server may not wish to provide the information to the particular requester, or a name server may not wish to perform a particular operation (e.g., zone transfer) for particular data. |
