Assembly: System (in System.dll)
public: [HostProtectionAttribute(SecurityAction::LinkDemand, ExternalThreading = true)] static Task<IPHostEntry^>^ GetHostEntryAsync( IPAddress^ address )
An IP address.
This operation will not block. The returned Task<TResult> object will complete after the address has been resolved.
This method queries a DNS server for the IP addresses and aliases associated with an IP address.
IPv6 addresses are filtered from the results of this 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.
