Constructor Details
#initialize(value_data, validate = true) ⇒ IpAddress
Create an IpAddress object. The constructor accepts either a raw four-octet string or a formatted string of integers separated by dots (i.e. “10.1.2.3”). Validation of the format can be disabled by setting the ‘validate’ flag to false.
