### Question:
IPTarget extends PGinet implements Serializable, Cloneable, Comparable<IPTarget> { public InetAddress getHost() { return host; } IPTarget();  IPTarget(PGinet ip);  IPTarget(byte[] address);  IPTarget(String ip); final void init(); @Override void setValue(String v); InetAddress getHost(); byte[] getAddr(); void setHost(InetAddress host); boolean isV6(); void setV6(boolean v6); @Override boolean equals(Object obj); @Override int hashCode(); @Override int compareTo(IPTarget o); byte[] getMAC(); InetAddress getUnicastPrefixMCAddress(); IPTarget getPrevious(); IPTarget getNext(); IPTarget getEmbeddedIPv4(); BigInteger subtract(IPTarget ip); IPTarget subtract(BigInteger offset); IPTarget subtract(long offset); IPTarget add(BigInteger offset); IPTarget add(long offset); boolean isMulticast(); boolean isMulticastGlobal(); boolean isMulticastLinkLocal(); boolean isMulticastNodeLocal(); boolean isMulticastOrgLocal(); boolean isMulticastSiteLocal(); boolean isLinkLocal(); boolean isAnyLocal(); boolean isLoopback(); @Override String toString(); static final InetAddress MAX_V4_ADDRESS; static final BigInteger MAX_V4_VALUE; static final InetAddress MAX_V6_ADDRESS; static final BigInteger MAX_V6_VALUE; }### Answer:
@Test public void testInitializerPGinet() throws Exception { IPTarget ip = new IPTarget(); Assert.assertEquals("Empty IPTarget must not have a host", null, ip.getHost()); }
