cidr4 :: V4HostAddress -> Word8 -> Maybe Cidr Source #

Make Cidr type of IPv4 from host-address bits consistent with mask

cidr4' :: V4HostAddress -> Word8 -> Maybe Cidr Source #

Same as cidr4 except for dropping host-address bits along with mask

cidr6 :: V6HostAddress -> Word8 -> Maybe Cidr Source #

Make Cidr type of IPv6 from host-address bits consistent with mask

cidr6' :: V6HostAddress -> Word8 -> Maybe Cidr Source #

Same as cidr6 except for dropping host-address bits along with mask

Definitions about the address type which is the pair of host-address and mask

data NetAddress Source #

IPv4 or IPv6 netword address corresponding host-addr/mask. eg. '192.168.0.1/24'

Definitions about the host-address types

data V4HostAddress Source #

Host address type along with IPv4 address bytes with IPv4 string order.

v4HostAddressOctets :: V4HostAddress -> (Word8, Word8, Word8, Word8) Source #

data V6HostAddress Source #

Host address type along with IPv6 address words with IPv6 string order. Each Word16 value is host byte order. Host byte order is portable in programs on its own host. Network byte order is only needed, when communicating other hosts.
