从接口复制的说明: DnsServerAddressStreamProvider

Ask this provider for the name servers to query for hostname.

指定者:

nameServerAddressStream 在接口中 DnsServerAddressStreamProvider

参数:

hostname - The hostname for which to lookup the DNS server addressed to use. If this is the final DnsServerAddressStreamProvider to be queried then generally empty string or '.' correspond to the default DnsServerAddressStream.

返回:
