# The IP Address Validator accepts the following options
# 
#   * allow_nil - allows nil values
#   * allow_blank - allows blank values
#   * allow_cidr - allows /prefixlen CIDR masks in values
#
# the validator will use regular expressions in an attempt to prevent
# malformed IP addresses from being passed to the IPAddr.new initializer
# as this method can be very slow to raise exceptions for malformed input.
