IP data

data IP Source #

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

Methods

masked :: a -> a -> a Source #

The masked function takes an Addr and a contiguous mask and returned a masked Addr.

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.
