network-data-0.2.1: Library for network data structures (ex: ip/udp/tcp headers and helper functions)

Safe HaskellSafe-Infered

Data.IP

Description

The Data.IP library exports IPv4 address and header structures.

FIXME: There is currently no support for options fields of the IP header.

Synopsis

Documentation

data IPv4 Source

For IPv4 addresses.

Constructors

IPv4 Word32 

Instances

data IPv4Header Source

This IPv4 header structure lacks support for options. Ints are used for most integral data types and the binary instance hands the bit packing.

No warning is provided if a value is trunkated when packed!

Constructors
