Domain
type Domain = ByteStringSource
Type for domain.
Resource Records
type ResourceRecord = RR RDATASource
Raw data format for resource records.
Constructors
| ResourceRecord | |
Raw data format for each type.
rrMapWithType :: (TYPE -> a -> b) -> RR a -> RR bSource
Resource Record Type
Types for resource records.
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. |
DNS Format
type DNSFormat = DNSMessage RDATASource
data DNSMessage a Source

Constructors
| DNSFormat | |
Instances
| Functor DNSMessage | |
| Foldable DNSMessage | |
| Traversable DNSMessage | |
| Eq a => Eq (DNSMessage a) | |
| Show a => Show (DNSMessage a) |
dnsMapWithType :: (TYPE -> a -> b) -> DNSMessage a -> DNSMessage bSource
dnsTraverseWithType :: Applicative f => (TYPE -> a -> f b) -> DNSMessage a -> f (DNSMessage b)Source
DNS Header
Raw data format for the header of DNS Query and Response.
Constructors
| DNSHeader | |
DNS Flags
Raw data format for the flags of DNS Query and Response.
Constructors
| DNSFlags | |
Fields
| |
DNS Body
Raw data format for DNS questions.
