Public Shared Function Resolve (hostName As String) As IPHostEntry

Parameters

hostName
String

A DNS-style host name or IP address.

Returns

IPHostEntry

An IPHostEntry instance that contains address information about the host specified in hostName.

Attributes
ObsoleteAttribute

Exceptions

ArgumentNullException

hostName is null.

ArgumentOutOfRangeException

The length of hostName is greater than 255 characters.

SocketException

An error is encountered when resolving hostName.

Remarks

The Resolve method queries a DNS server for the IP address associated with a host name or IP address.

When hostName is a DNS-style host name associated with multiple IP addresses, only the first IP address that resolves to that host name is returned.

If the Ipv6Element.Enabled property is set to true, the Aliases property of the IPHostEntry instance returned is not populated by this method and will always be empty.

Note

This member emits trace information when you enable network tracing in your application. For more information, see Network Tracing in .NET Framework.
