Instance Method Details

#bitness_max(bitness) ⇒ Object

Masks off all but the bitness most-significant-bits, filling with ones

Examples:

/24 fills the last quad

IpAddress.new('1.2.3.4').bitness_min(24) # '1.2.3.255'

Raises:



20
21
22
23
 
# File 'lib/gorillib/type/ip_address.rb', line 20

def bitness_max(bitness)
  raise ArgumentError, "IP addresses have only 32 bits (got #{bitness.inspect})" unless (0..32).include?(bitness)
  packed | (ONES >> bitness)
end

#bitness_min(bitness) ⇒ Object

Masks off all but the bitness most-significant-bits

Examples:

/24 keeps only the first three quads

IpAddress.new('1.2.3.4').bitness_min(24) # '1.2.3.0'

Raises:
