Pointer (PTR) RRs are used to help the reverse lookup procedure, depending on zones produced and rooted inside the in-addr.arpa area. These documents are accustomed to Identify a computer by its IP handle and resolve this information into the DNS domain identify for that computer.
Whenever we invoke Java, we specify the title of the appliance to run: org.mypackage.HelloWorld. On the other hand we have to also convey to Java where by to look for the information and directories defining our deal. So to start This system, we have to use the next command:
