Dns.GetHostEntry Method (IPAddress)
Resolves an IP address to an IPHostEntry instance.
Assembly: System (in System.dll)
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.
