When a security manager is not installed, the defaultД«ehavior is to cache entries for a finite (implementation dependent) The result of positive host name resolutions areД¬ached forever. The InetAddress class has a cache to store successful as well asД«y default, when a security manager is installed, in order to

The InetAddress class provides methods to resolve host names to The host associated with the IP address is returned. Reverse name resolution means that for any IP address, For any host name, its corresponding IP address is returned. Services(s) being used is by default the local machine configured The use of a combination of local machine configuration informationДЄnd network naming services such as the Domain Name System (DNS)ДЄnd Network Information Service(NIS). Host name-to-IP address resolution is accomplished through System Properties affecting how IPv4 and IPv6 addresses are used. The textual representation of an IP address is address family specific.ДЇor IPv4 address format, please refer to Inet4Address#format For IPv6ДЄddress format, please refer to Inet6Address#format. Global addresses are unique across the internet. Inside of a site without the need for a global prefix. Site-local addresses are designed to be used for addressing Neighbor discovery, or when no routers are present. On a single link for purposes such as auto-address configuration, Link-local addresses are designed to be used for addressing A packet sent to a multicast address isДelivered to all interfaces identified by that address. This address is often used when testing aДЄn identifier for a set of interfaces (typically belonging IP address loops around and becomes IP input on the local The Loopback Addresses - This is the addressДЄssigned to the loopback interface. The unspecified address must not be used as Interface, in case the server host has multiple interfaces. One example of its use is as the target ofД«ind, which allows a server to accept a client connection on any The Unspecified Address - Also called anylocal or wildcardДЄddress. A packet sent toДЄ unicast address is delivered to the interface identified by With a host name or whether it has already done reverse host nameДЄn identifier for a single interface. InetAddress consists of an IP address and possibly itsД¬orresponding host name (depending on whether it is constructed The IP address architecture is defined by RFCВ 790:ДЄddress Allocation for Private Internets, RFCВ 2365:ДЄdministratively Scoped IP Multicast, and RFCВ 2373: IP Used by IP, a lower-level protocol on which protocols like UDP and This class represents an Internet Protocol (IP) address.ДЄn IP address is either a 32-bit or 128-bit unsigned number
