You create a reverse-lookup zone in much the same way that you create a forward-lookup zone. The primary difference is that you specify the subnet for the zone, and the DNS console converts that to the appropriate reverse zone name. Enter 208.141.230 after you're prompted, for example, and the DNS console creates the reverse lookup zone 230.141.208.in-addr.arpa. You do not need to specify three octets unless you're creating a reverse-lookup zone for a domain that uses a class-C address space. Specify the appropriate number of octets to define your reverse lookup zone. In addition, you can choose to specify the DNS filename yourself, but remember to enter it in reverse notation.
