InetAddress

data InetAddress

To avoid errors with endianess it was decided to keep this type abstract.

Use inetAddressFromTuple and inetAddressToTuple for constructing and deconstructing custom addresses.

Hint: Use the Storable instance. It exposes it exactly as found within an IP packet (big endian if you insist on interpreting it as a number).

Another hint: Use getAddressInfo for parsing and suppress nameserver lookups:

> getAddressInfo (Just "127.0.0.1") Nothing aiNumericHost :: IO [AddressInfo Inet Stream TCP]
[AddressInfo {addressInfoFlags = AddressInfoFlags 4, socketAddress = SocketAddressInet {inetAddress = InetAddress 127.0.0.1, inetPort = InetPort 0}, canonicalName = Nothing}]

data family SocketAddress f

The SocketAddress type is a data family. This allows to provide different data constructors depending on the socket family without knowing all of them in advance or the need to extend this core library.
