The IPHostEntry class associates a Domain Name System (DNS) host name with an array of aliases and an array of matching IP addresses.

The IPHostEntry class is used as a helper class with the Dns class.

The following example queries the DNS database for information on the host www.contoso.com and returns the information in an IPHostEntry instance.


Dim hostInfo As IPHostEntry = Dns.GetHostByName("www.contoso.com")
