Assembly: System (in System.dll)
'Declaration Public Shared Function GetHostEntry ( _ address As IPAddress _ ) As IPHostEntry
- Type: System.Net.IPAddress
An IP address.
The GetHostEntry method queries a DNS server for the IP addresses and aliases associated with an IP address.
IPv6 addresses are filtered from the results of the GetHostEntry method if the local computer does not have IPv6 installed. As a result, it is possible to get back an empty IPHostEntry instance if only IPv6 results where available for the address parameter.
This member emits trace information when you enable network tracing in your application. For more information, see Network Tracing in the .NET Framework.
