Inet4Address

class Inet4Address : InetAddress
kotlin.Any
   ↳ java.net.InetAddress
   ↳ java.net.Inet4Address

This class represents an Internet Protocol version 4 (IPv4) address. Defined by RFC 790: Assigned Numbers, RFC 1918: Address Allocation for Private Internets, and RFC 2365: Administratively Scoped IP Multicast

Textual representation of IP addresses

Textual representation of IPv4 address used as input to methods takes one of the following forms:
  • d.d.d.d
  • d.d.d
  • d.d
  • d

When four parts are specified, each is interpreted as a byte of data and assigned, from left to right, to the four bytes of an IPv4 address.

When a three part address is specified, the last part is interpreted as a 16-bit quantity and placed in the right most two bytes of the network address. This makes the three part address format convenient for specifying Class B net- work addresses as 128.net.host.

When a two part address is supplied, the last part is interpreted as a 24-bit quantity and placed in the right most three bytes of the network address. This makes the two part address format convenient for specifying Class A network addresses as net.host.

When only one part is given, the value is stored directly in the network address without any byte rearrangement.

For methods that return a textual representation as output value, the first form, i.e. a dotted-quad string, is used.

The Scope of a Multicast Address

Historically the IPv4 TTL field in the IP header has doubled as a multicast scope field: a TTL of 0 means node-local, 1 means link-local, up through 32 means site-local, up through 64 means region-local, up through 128 means continent-local, and up through 255 are global. However, the administrative scoping is preferred. Please refer to RFC 2365: Administratively Scoped IP Multicast

Inherited functions

Public methods

equals

Added in API level 1
fun equals(other: Any?): Boolean

Compares this object against the specified object. The result is true if and only if the argument is not null and it represents the same IP address as this object.

Two instances of InetAddress represent the same IP address if the length of the byte arrays returned by getAddress is the same for both, and each of the array components is the same for the byte arrays.

Parameters
obj the object to compare against.
Return
Boolean true if the objects are the same; false otherwise.

getAddress

Added in API level 1
fun getAddress(): ByteArray!

Returns the raw IP address of this InetAddress object. The result is in network byte order: the highest order byte of the address is in getAddress()[0].

Return
ByteArray! the raw IP address of this object.

getHostAddress

Added in API level 1
fun getHostAddress(): String?

Returns the IP address string in textual presentation form.

Return
String? the raw IP address in a string format.

hashCode

Added in API level 1
fun hashCode(): Int

Returns a hashcode for this IP address.

Return
Int a hash code value for this IP address.

isAnyLocalAddress

Added in API level 1
fun isAnyLocalAddress(): Boolean

Utility routine to check if the InetAddress is a wildcard address.

Return
Boolean a boolean indicating if the Inetaddress is a wildcard address.

isLinkLocalAddress

Added in API level 1
fun isLinkLocalAddress(): Boolean

Utility routine to check if the InetAddress is an link local address.

Return
Boolean a boolean indicating if the InetAddress is a link local address; or false if address is not a link local unicast address.

isLoopbackAddress

Added in API level 1
fun isLoopbackAddress(): Boolean

Utility routine to check if the InetAddress is a loopback address.

Return
Boolean a boolean indicating if the InetAddress is a loopback address; or false otherwise.

isMCGlobal

Added in API level 1
fun isMCGlobal(): Boolean

Utility routine to check if the multicast address has global scope.

Return
Boolean a boolean indicating if the address has is a multicast address of global scope, false if it is not of global scope or it is not a multicast address

isMCLinkLocal

Added in API level 1
fun isMCLinkLocal(): Boolean

Utility routine to check if the multicast address has link scope.

Return
Boolean a boolean indicating if the address has is a multicast address of link-local scope, false if it is not of link-local scope or it is not a multicast address

isMCNodeLocal

Added in API level 1
fun isMCNodeLocal(): Boolean

Utility routine to check if the multicast address has node scope.

Return
Boolean a boolean indicating if the address has is a multicast address of node-local scope, false if it is not of node-local scope or it is not a multicast address

isMCOrgLocal

Added in API level 1
fun isMCOrgLocal(): Boolean

Utility routine to check if the multicast address has organization scope.

Return
Boolean a boolean indicating if the address has is a multicast address of organization-local scope, false if it is not of organization-local scope or it is not a multicast address

isMCSiteLocal

Added in API level 1
fun isMCSiteLocal(): Boolean

Utility routine to check if the multicast address has site scope.

Return
Boolean a boolean indicating if the address has is a multicast address of site-local scope, false if it is not of site-local scope or it is not a multicast address

isMulticastAddress

Added in API level 1
fun isMulticastAddress(): Boolean

Utility routine to check if the InetAddress is an IP multicast address. IP multicast address is a Class D address i.e first four bits of the address are 1110.

Return
Boolean a boolean indicating if the InetAddress is an IP multicast address

isSiteLocalAddress

Added in API level 1
fun isSiteLocalAddress(): Boolean

Utility routine to check if the InetAddress is a site local address.

Return
Boolean a boolean indicating if the InetAddress is a site local address; or false if address is not a site local unicast address.
