IP data
A unified IP data for IPv4
and IPv6
.
To create this, use the data constructors. Or use read
"192.0.2.1"
:: IP
, for example. Also, "192.0.2.1"
can be used as literal with OverloadedStrings.
>>>
(read "192.0.2.1" :: IP) == IPv4 (read "192.0.2.1" :: IPv4)
True>>>
(read "2001:db8:00:00:00:00:00:01" :: IP) == IPv6 (read "2001:db8:00:00:00:00:00:01" :: IPv6)
True

IPv4
fromHostAddress :: HostAddress -> IPv4 Source #
The fromHostAddress
function converts HostAddress
to IPv4
.
toHostAddress :: IPv4 -> HostAddress Source #
The toHostAddress
function converts IPv4
to HostAddress
.
IPv6
The abstract data type to express an IPv6 address.
To create this, use toIPv6
. Or use read
"2001:DB8::1"
:: IPv6
, for example. Also, "2001:DB8::1"
can be used as literal with OverloadedStrings.
>>>
read "2001:db8:00:00:00:00:00:01" :: IPv6
2001:db8::1>>>
read "2001:db8:11e:c00::101" :: IPv6
2001:db8:11e:c00::101>>>

read "::0.0.0.1" :: IPv6
::1
fromHostAddress6 :: HostAddress6 -> IPv6 Source #
The fromHostAddress6
function converts HostAddress6
to IPv6
.
toHostAddress6 :: IPv6 -> HostAddress6 Source #
The toHostAddress6
function converts IPv6
to HostAddress6
.
Converters
ipv4ToIPv6 :: IPv4 -> IPv6 Source #
Convert IPv4 address to IPv4-embedded-in-IPv6
fromSockAddr :: SockAddr -> Maybe (IP, PortNumber) Source #
IP range data
A unified data for AddrRange
IPv4
and AddrRange
IPv6
.
To create this, use read
"192.0.2.0/24"
:: IPRange
.
Also, "192.0.2.0/24"
can be used as literal with OverloadedStrings.
>>>
(read "192.0.2.1/24" :: IPRange) == IPv4Range (read "192.0.2.0/24" :: AddrRange IPv4)
True>>>
(read "2001:db8:00:00:00:00:00:01/48" :: IPRange) == IPv6Range (read "2001:db8:00:00:00:00:00:01/48" :: AddrRange IPv6)
True
The Addr range consists of an address, a contiguous mask, and mask length. The contiguous mask and the mask length are essentially same information but contained for pre calculation.
To create this, use makeAddrRange
or read
"192.0.2.0/24"
:: AddrRange
IPv4
.
Also, "192.0.2.0/24"
can be used as literal with OverloadedStrings.
>>>
read "192.0.2.1/24" :: AddrRange IPv4
192.0.2.0/24>>>
read "2001:db8:00:00:00:00:00:01/48" :: AddrRange IPv6

>>>
toIPv4 [127,0,2,1] `masked` intToMask 7
126.0.0.0
masked :: a -> a -> a Source #
intToMask :: Int -> a Source #
The intToMask
function takes an Int
representing the number of bits to
be set in the returned contiguous mask. When this integer is positive the
bits will be starting from the MSB and from the LSB otherwise.

intToMask (-16) :: IPv6

makeAddrRange :: Addr a => a -> Int -> AddrRange a Source #
The makeAddrRange
functions takes an Addr
address and a mask
length. It creates a bit mask from the mask length and masks
the Addr
address, then returns AddrRange
made of them.
>>>
makeAddrRange (toIPv4 [127,0,2,1]) 8

2000::/8
(>:>) :: Addr a => AddrRange a -> AddrRange a -> Bool Source #
The >:> operator takes two AddrRange
. It returns True
if
the first AddrRange
contains the second AddrRange
. Otherwise,
it returns False
.

False
isMatchedTo :: Addr a => a -> AddrRange a -> Bool Source #
The toMatchedTo
function take an Addr
address and an AddrRange
,
and returns True
if the range contains the address.
