An IPv4 data type
This module provides the IPv4 data type and functions for working
with it. There are also encoding and decoding functions provided
in this module, but they should be imported from
Net.IPv4.Text
and Net.IPv4.ByteString.Char8
instead. They are
defined here so that the FromJSON
and ToJSON
instances can
use them.
At some point, a highly efficient IPv4-to-ByteString function needs
to be added to this module to take advantage of aeson
's new
toEncoding
method.
Conversion Functions
fromOctets :: Word8 -> Word8 -> Word8 -> Word8 -> IPv4 Source
Create an IPv4
address from four octets. The first argument
is the most significant octet. The last argument is the least
significant.
Since the Show
and Read
instances for IPv4
are not generally
usefully, this function is the recommened way to create IPv4
addresses.
For example:
>>>
fromOctets 192 168 1 1
IPv4 {getIPv4 = 3232235777}
toOctets :: IPv4 -> (Word8, Word8, Word8, Word8) Source
Convert an IPv4
address into a quadruple of octets. The first
element in the quadruple is the most significant octet. The last
element is the least significant octet.
Special IP Addresses
Range Predicates
private :: IPv4 -> Bool Source
Checks to see if the IPv4
address belongs to a private
network. The three private networks that are checked are
10.0.0.0/8
, 172.16.0.0/12
, and 192.168.0.0/16
.
