Constructor Detail

def self.loopback : self #

Constructs a IP::Block:IPv4 representing the IPv4 loopback block.


[View source]
def self.new(address : IP::Address::IPv4, block : Int) : self #

Constructs a new IP::Block::IPv4 from an address and the block size, [0-32].

Raises: MalformedError when the input is malformed.


[View source]
def self.new(string : String) : self #

Constructs a new IP::Block::IPv4 by interpreting the contents of a given String.

Expects a definition in CIDR notation similar to [0-255].[0-255].[0-255].[0-255]/[0-32].

Raises: MalformedError when the input is malformed.


[View source]
def self.new?(address : IP::Address::IPv4, block : Int) : self? #

Constructs a new IP::Block::IPv4 from an address and the block size, [0-32].

Returns nil when the input is malformed.


[View source]
def self.new?(string : String) : self? #

Constructs a new IP::Block::IPv4 by interpreting the contents of a given String.

Expects a definition in CIDR notation similar to [0-255].[0-255].[0-255].[0-255]/[0-32]

Returns nil when the input is malformed.

Instance Method Detail

def address : IP::Address::IPv4 #

Returns the address component of the block which is also the first address.


[View source]
def block : UInt8 #

Returns 'block' size in the form of 2^x, x being the 'size'.


[View source]
def ipv4? : Bool #

Informs if the block is IPv4 or not.


[View source]
def size : UInt32 #

Returns the size of the block in terms of number of addresses.
