All Implemented Interfaces:

Type

public class IPv4Type
extends StringType

Internet Protocol Version 4 or short IPv4 mapped onto a string.

The IPv4Type holds an IPv4 address in dotted quad notation. Constraint checking ensures that the value complies to the syntax `d.d.d.d', where `d' is a number from [0, 255].
