• "192.168." - represents an IP address-based subnet
• "localhost.domain.com" - represents a single hostname
• ".domain.com" - represents all hosts within the given domain
• "*" - represents all internet hosts

Field Summary

static int	ALL This constant represents a range of all internet hosts.
static int	DOMAIN This constant represents a domain-based range.
static int	IPADDR This constant represents an IP-based range.
protected java.lang.String	range The host range string.
protected boolean	single Whether this range represents a single host or a subnet/domain.
protected int	type The host range type.

Constructor Summary

InetHost(java.lang.String range)
Creates a new InetHost with the given range.

Method Summary

boolean	equals(java.lang.Object obj)
java.lang.String	getRange() Returns the host range string.
int	getType() Returns the host range type.
int	hashCode()
boolean	implies(java.net.InetAddress addr) Tests whether the given address is within the range represented by this object.
