给定一个域,使用JAVA或PYTHON查找其宿主提供程序
给定一个域,如何查找其托管提供商。我以前在Java中做过IP的NSlookup,但是有没有办法也找到主机提供商呢?谢谢试试这个:给定一个域,使用JAVA或PYTHON查找其宿主提供程序,java,python,hosting,provider,Java,Python,Hosting,Provider,给定一个域,如何查找其托管提供商。我以前在Java中做过IP的NSlookup,但是有没有办法也找到主机提供商呢?谢谢试试这个: import java.net.InetAddress; import java.net.UnknownHostException; import org.xbill.DNS.ExtendedResolver; import org.xbill.DNS.Lookup; import org.xbill.DNS.Name; import org.xbill.DNS.PT

输出:
