示例1: notation
Try
' Call the Resolve method passing a DNS style host name or an IP address in
' dotted-quad notation (for example, "www.contoso.com" or "207.46.131.199") to
' obtain an IPHostEntry instance that contains address information for the
' specified host.
Dim hostInfo As IPHostEntry = Dns.Resolve(hostString)
' Get the IP address list that resolves to the host names contained in the Alias
' property.
Dim address As IPAddress() = hostInfo.AddressList
' Get the alias names of the addresses in the IP address list.
Dim [alias] As [String]() = hostInfo.Aliases
Console.WriteLine(("Host name : " + hostInfo.HostName))
Console.WriteLine(ControlChars.Cr + "Aliases : ")
Dim index As Integer
For index = 0 To [alias].Length - 1

Next index
Console.WriteLine(ControlChars.Cr + "IP Address list :")
For index = 0 To address.Length - 1
