Domain Name System (DNS) servers can enable clients to determine the DNS name of a host based on the host's IP address by providing a special zone called a reverse lookup zone. A reverse lookup zone contains pointer (PTR) resource records that map IP addresses to the host name. Some applications, such as secure Web applications, rely on reverse lookups. Create a reverse lookup zone only if applications running on your network require it. Otherwise, disable dynamic updates for pointer (PTR) resource records by client computers.
