Domain
type Domain = ByteString Source
Type for domain.
Resource Records
data ResourceRecord Source
Raw data format for resource records.
Constructors
| ResourceRecord | |
| OptRecord | |
Instances
Raw data format for each type.
Constructors
| OD_ClientSubnet Int Int IP | |
| OD_Unknown Int ByteString |
Resource Record Type
Types for resource records.
intToOptType :: Int -> OPTTYPE Source
optTypeToInt :: OPTTYPE -> Int Source
DNS Error
An enumeration of all possible DNS errors that can occur.
Constructors
| 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. |
| BadOptRecord | The server detected a malformed OPT RR. |
DNS Message
data DNSMessage Source
Raw data format for DNS Query and Response.
Constructors
| DNSMessage | |
Fields
| |
Instances
type DNSFormat = DNSMessage Source
For backward compatibility.
DNS Header
Raw data format for the header of DNS Query and Response.
Constructors
| DNSHeader | |
Fields
| |
DNS Flags
Raw data format for the flags of DNS Query and Response.
Constructors
| DNSFlags | |
Fields
| |
DNS Body
Raw data format for DNS questions.
responseAAAA :: Int -> Question -> [IPv6] -> DNSMessage Source
