 java.net.InetAddress
java.net.Inet4Address
| Method Summary | |
| public boolean | equals(Object obj)
Returns true if obj is of the same type as the IPv4 address and they have
the same IP address, false otherwise. | | public String | getHostAddress()
Returns a String representation of the IP address. | | public int | hashCode()
Overrides the basic hashcode function. | | public boolean | isAnyLocalAddress()
| | public boolean | isLinkLocalAddress()
Answers whether this address has link-local scope. | | public boolean | isLoopbackAddress()
Answers true if the address is a loopback address. | | public boolean | isMCGlobal()
Answers true if an address is a global multicast address. | | public boolean | isMCLinkLocal()
| | public boolean | isMCNodeLocal()
Answers false for all IPv4 addresses. | | public boolean | isMCOrgLocal()
Answers true if the address is a organization-local address. | | public boolean | isMCSiteLocal()
Answers true if the address is a site-local address.The valid range for
IPv4 site-local addresses is: 239.255.0.0 to 239.255.255.255 Hence a mask
of 11101111 11111111 = 0xEFFF. | | public boolean | isMulticastAddress()
Answers true if the address is a multicast address. | | public boolean | isSiteLocalAddress()
Answers whether this address has site-local scope. |
| Inet4Address | | Inet4Address(byte[] address)(Code) | | |
| Inet4Address | | Inet4Address(byte[] address, String name)(Code) | | |
| equals | | public boolean equals(Object obj)(Code) | | Returns true if obj is of the same type as the IPv4 address and they have
the same IP address, false otherwise.
true if equal and false otherwise |
| getHostAddress | | public String getHostAddress()(Code) | | Returns a String representation of the IP address.
Host address |
| hashCode | | public int hashCode()(Code) | | Overrides the basic hashcode function.
the hash code |
| isAnyLocalAddress | | public boolean isAnyLocalAddress()(Code) | | Answers if the address is the ANY Address
boolean |
| isLinkLocalAddress | | public boolean isLinkLocalAddress()(Code) | | Answers whether this address has link-local scope.
RFC 3484 Default Address Selection for Internet Protocol version 6 (IPv6)
states IPv4 auto-configuration addresses, prefix 169.254/16, IPv4
loopback addresses, prefix 127/8, are assigned link-local scope.
boolean |
| isLoopbackAddress | | public boolean isLoopbackAddress()(Code) | | Answers true if the address is a loopback address. Loopback ipv4
addresses are prefixed with: 011111111 = 127
boolean |
| isMCGlobal | | public boolean isMCGlobal()(Code) | | Answers true if an address is a global multicast address. Valid MCGlobal
IPv4 addresses are 224.0.1.0 - 238.255.255.255
boolean true, if the address is in the global multicast group,false otherwise |
| isMCLinkLocal | | public boolean isMCLinkLocal()(Code) | | Answers true if the address is a link-local address.The valid range for
IPv4 link-local addresses is: 224.0.0.0 to 239.0.0.255 Hence a mask of
111000000000000000000000 = 0xE00000
boolean |
| isMCNodeLocal | | public boolean isMCNodeLocal()(Code) | | Answers false for all IPv4 addresses. There are no valid IPv4 Node-local
addresses
boolean |
| isMCOrgLocal | | public boolean isMCOrgLocal()(Code) | | Answers true if the address is a organization-local address. The valid
range for IPv4 org-local addresses is: 239.192.0.0 to 239.195.255.255
Hence masks of 11101111 11000000 to 11101111 11000011 are valid. 0xEFC0
to 0xEFC3
true if org local address, false otherwise |
| isMCSiteLocal | | public boolean isMCSiteLocal()(Code) | | Answers true if the address is a site-local address.The valid range for
IPv4 site-local addresses is: 239.255.0.0 to 239.255.255.255 Hence a mask
of 11101111 11111111 = 0xEFFF.
boolean |
| isMulticastAddress | | public boolean isMulticastAddress()(Code) | | Answers true if the address is a multicast address. Valid IPv4 multicast
addresses are prefixed with 1110 = 0xE
boolean |
| isSiteLocalAddress | | public boolean isSiteLocalAddress()(Code) | | Answers whether this address has site-local scope. RFC 3484 Default
Address Selection for Internet Protocol version 6 (IPv6) states IPv4
private addresses, prefixes 10/8, 172.16/12, and 192.168/16, are assigned
site-local scope.
