Constructors

IPAddress(byte[])

Initializes a new instance of the IPAddress class with the address specified as a Byte array.

public IPAddress(byte[] address)

Parameters

address byte[]

The byte array value of the IP address.

Remarks

The IPAddress is created with the System.Net.IPAddress.Address property set to address. If the length of address is 4, IPAddress(Byte[]) constructs an IPv4 address; otherwise, an IPv6 address with a scope of 0 is constructed. The byte array is assumed to be in network byte order with the most significant byte first in index position 0.

Exceptions

ArgumentNullException

address is null.

ArgumentException

address contains a bad IP address.

IPAddress(byte[], long)

Initializes a new instance of a IPV6 IPAddress class with the address specified as a Byte array.

public IPAddress(byte[] address, long scopeid)

Parameters

address byte[]

The byte array value of the IP address.

scopeid long

The long value of the scope identifier.

Remarks

The IPAddress is created with the System.Net.IPAddress.Address property set to address. If the length of address is 4, IPAddress(Byte[]) constructs an IPv4 address; otherwise, an IPv6 address with a scope of 0 is constructed. The byte array is assumed to be in network byte order with the most significant byte first in index position 0.

Exceptions

ArgumentNullException

address is null.

ArgumentException

address contains a bad IP address.

IPAddress(long)

Initializes a new instance of the IPAddress class with the address specified as an Int64.

public IPAddress(long newAddress)

Parameters

newAddress long

The long value of the IP address. For example, the value 0x2414188f in big-endian format would be the IP address "143.24.20.36".

Remarks

The IPAddress instance is created with the System.Net.IPAddress.Address property set to newAddress. The long value is assumed to be in network byte order.

Exceptions

ArgumentOutOfRangeException

newAddress < 0 or newAddress > 0x00000000FFFFFFFF

Fields

Any

Provides an IP address that indicates that the server must listen for client activity on all network interfaces. This field is read-only.

public static readonly IPAddress Any

Field Value

IPAddress

Remarks

The Bind(EndPoint) method uses the Any field to indicate that a Socket instance must listen for client activity on all network interfaces.

The Any field is equivalent to 0.0.0.0 in dotted-quad notation.

Broadcast

Provides the IP broadcast address. This field is read-only.

public static readonly IPAddress Broadcast

Field Value

IPAddress

Remarks

The Broadcast field is equivalent to 255.255.255.255 in dotted-quad notation.

IPv6Any

The Bind(EndPoint) method uses the IPv6Any field to indicate that a Socket must listen for client activity on all network interfaces.

public static readonly IPAddress IPv6Any

Field Value

IPAddress

IPv6Loopback

Provides the IP loopback address. This property is read-only.

public static readonly IPAddress IPv6Loopback

Field Value

IPAddress

Loopback

Provides the IP loopback address. This field is read-only.

public static readonly IPAddress Loopback

Field Value

IPAddress

Remarks

The Loopback field is equivalent to 127.0.0.1 in dotted-quad notation.

None

Provides an IP address that indicates that no network interface should be used. This field is read-only.

public static readonly IPAddress None

Field Value

IPAddress

Remarks

The Bind(EndPoint) uses the None field to indicate that a Socket must not listen for client activity.

The None field is equivalent to 255.255.255.255 in dotted-quad notation.

Properties

AddressFamily

Gets the address family of the IP address.

public AddressFamily AddressFamily { get; }

Property Value

AddressFamily

Returns InterNetwork for IPv4 or InterNetworkV6 for IPv6.

IsIPv4MappedToIPv6

Gets whether the IP address is an IPv4-mapped IPv6 address.

public bool IsIPv4MappedToIPv6 { get; }

Property Value

bool

true if the IP address is an IPv4-mapped IPv6 address; otherwise, false.

ScopeId

Get or Set IPV6 scope identifier.

public long ScopeId { get; set; }

Property Value

long

Methods

Equals(IPAddress)

Compares two IP addresses.

public bool Equals(IPAddress other)

Parameters

other IPAddress

An IPAddress instance to compare to the current instance.

Returns

bool

true if the two addresses are equal; otherwise, false.

Equals(object)

Compares two IP addresses.

public override bool Equals(object other)

Parameters

other object

An IPAddress instance to compare to the current instance.

Returns

bool

true if the two addresses are equal; otherwise, false.

GetAddressBytes()

Provides a copy of the IPAddress as an array of bytes in network order.

public byte[] GetAddressBytes()

Returns

byte[]

A byte array.

GetDefaultLocalAddress()

Retrieves an IP address that is the local default address.

public static IPAddress GetDefaultLocalAddress()

Returns

IPAddress

The default IP address.

GetHashCode()

Serves as the default hash function.

public override int GetHashCode()

Returns

int

A hash code for the current object.

MapToIPv4()

Maps the IPAddress object to an IPv4 address.

public IPAddress MapToIPv4()

Returns

IPAddress

Returns IPAddress. An IPV4 address.

Remarks

Dual-stack sockets always require IPv6 addresses. The ability to interact with an IPv4 address requires the use of the IPv4-mapped IPv6 address format.

MapToIPv6()

Maps the IPAddress object to an IPv6 address.

public IPAddress MapToIPv6()

Returns

IPAddress

Returns IPAddress. An IPV6 address.

Remarks

Dual-stack sockets always require IPv6 addresses. The ability to interact with an IPv4 address requires the use of the IPv4-mapped IPv6 address format. Any IPv4 addresses must be represented in the IPv4-mapped IPv6 address format which enables an IPv6 only application to communicate with an IPv4 node. For example. IPv4 192.168.1.4 maps as IPV6 ::FFFF:192.168.1.4

Parse(string)

Converts an IP address string to an IPAddress instance.

public static IPAddress Parse(string ipString)

Parameters

ipString string

A string that contains an IP address in dotted-quad notation for IPv4 and in colon-hexadecimal notation for IPv6.

Returns

IPAddress

An IPAddress instance.

ToString()

Converts an Internet address to its standard notation.

public override string ToString()

Returns

string

A string that contains the IP address in either IPv4 dotted-quad or in IPv6 colon-hexadecimal notation.

Remarks

The ToString() method converts the IP address that is stored in the System.Net.IPAddress.Address property to either IPv4 dotted-quad or IPv6 colon-hexadecimal notation.

Operators

operator ==(IPAddress, IPAddress)

Indicates whether two IPAddress objects are equal.

public static bool operator ==(IPAddress a, IPAddress b)

Parameters

a IPAddress

The IPAddress to compare with b.

b IPAddress

The IPAddress to compare with a.

Returns

bool

true if b is equal to a; otherwise, false.

operator !=(IPAddress, IPAddress)

Indicates whether two IPAddress objects are not equal.

public static bool operator !=(IPAddress a, IPAddress b)

Parameters

a IPAddress

The IPAddress to compare with b.

b IPAddress

The IPAddress to compare with a.

Returns

bool

true if b is not equal to a; otherwise, false.
