IpAddr

const class IpAddr : Obj

IpAddr models both IPv4 and IPv6 numeric addresses as well as provide DNS hostname resolution.

constructors

make	Parse an IP address formated as an IPv4 numeric address, IPv6 numeric address, or a DNS hostname.

methods

bytes	Get the raw bytes of this address as a Buf of 4 or 16 bytes for IPv4 or IPv6 respectively.
equals	Equality is based on equivalent address bytes.
hash	Hash code is based the address bytes.
hostname	Return the hostname of this address.
isIPv4	Is this a 32 bit (four byte) IP version 4 address.
isIPv6	Is this a 128 bit (sixteen byte) IP version 6 address.
isLoopback	Is this a loopback address.
isSiteLocal	Is this a site local address.
local	Return the IpAddr for the local machine.
makeAll	Resolve a hostname to all of its configured IP addresses.
makeBytes	Make an IpAddr for the specified raw bytes.
numeric	Get this address as a Str in its numeric notation.
toNative	To the native platform representation
toStr	Return the exact string passed to the constructor.

Slot Details

bytes

Buf bytes()

Get the raw bytes of this address as a Buf of 4 or 16 bytes for IPv4 or IPv6 respectively. The buf position is zero.

equals

virtual override Bool equals(Obj? obj)

Equality is based on equivalent address bytes.

hash

virtual override Int hash()

Hash code is based the address bytes.

hostname

Str hostname()

Return the hostname of this address. If a hostname was specified in make, then that string is used. Otherwise this method will perform a reverse DNS lookup potentially blocking the calling thread. If the address cannot be mapped to a hostname, then return the address in its numeric format.

isIPv4

Bool isIPv4()

Is this a 32 bit (four byte) IP version 4 address.

isIPv6

Bool isIPv6()

Is this a 128 bit (sixteen byte) IP version 6 address.

isLoopback

Bool isLoopback()

Is this a loopback address.

isSiteLocal

Bool isSiteLocal()

Is this a site local address.

local

static IpAddr local()

Return the IpAddr for the local machine.

make

static new make(Str s)

Parse an IP address formated as an IPv4 numeric address, IPv6 numeric address, or a DNS hostname. If a hostname if provided, then it is resolved to an IP address potentially blocking the calling thread. If the address is invalid or a hostname cannot be resolved then UnknownHostErr is thrown.

Examples:

IpAddr("169.200.3.103")
IpAddr("1080:0:0:0:8:800:200C:417A")
IpAddr("1080::8:800:200C:417A")
IpAddr("::ffff:129.144.52.38")
IpAddr("somehost")
IpAddr("www.acme.com")

makeAll

static IpAddr[] makeAll(Str s)

Resolve a hostname to all of its configured IP addresses. If a numeric IPv4 or IPv6 address is specified then a list of one IpAddr is returned. If a hostname if provided, then it is resolved to all its configured IP addresses potentially blocking the calling thread. If the address is invalid or a hostname cannot be resolved then UnknownHostErr is thrown.

makeBytes

static IpAddr makeBytes(Buf bytes)

Make an IpAddr for the specified raw bytes. The size of the byte buffer must be 4 for IPv4 or 16 for IPv6, otherwise ArgErr is thrown. The bytes must be a memory backed buffer.

numeric

Str numeric()

Get this address as a Str in its numeric notation. For IPv4 this is four decimal digits separated by dots. For IPv6 this is eight hexadecimal digits separated by colons.

toNative

Obj toNative()

To the native platform representation:

Java: returns java.net.InetAddress
.NET: returns System.Net.IPAddress

toStr

virtual override Str toStr()

Return the exact string passed to the constructor.
