Dns.EndGetHostAddresses Method

Ends an asynchronous request for DNS information.

Namespace:  System.Net
Assembly:  System (in System.dll)

'Declaration
Public Shared Function EndGetHostAddresses ( _
	asyncResult As IAsyncResult _
) As IPAddress()

Parameters

asyncResult
Type: System.IAsyncResult

An IAsyncResult instance returned by a call to the BeginGetHostAddresses method.

Return Value

Type: System.Net.IPAddress()
An array of type IPAddress that holds the IP addresses for the host specified by the hostNameOrAddress parameter of BeginGetHostAddresses.

The BeginGetHostAddresses method queries a DNS server for the IP addresses associated with a host name. If hostNameOrAddress is an IP address, this address is returned without querying the DNS server.

When an empty string is passed as the host name, this method returns the IPv4 addresses of the local host for all operating systems except Windows Server 2003; for Windows Server 2003, both IPv4 and IPv6 addresses for the local host are returned.
