Dns forward lookup zone not updating server 2016
If you own one class C address, and you want to distribute the addresses in the range to several different groups (for example, branch offices), but you do not want to manage the reverse lookup zones for those addresses, you would create classless reverse lookup zones and delegate them to those groups.
For example, suppose that an ISP has a class C address and has given the first 62 addresses to Reskit.
Table 6.3 shows how to configure your network with each type of subnet.
Table 6.3 Planning Reverse Lookup Zones Windows 2000-based clients and Windows 2000 DHCP servers can automatically add PTR resource records, or you can configure PTR resource records at the same time as when you create A resource records; otherwise, you might want to add PTR resource records manually.
The Active Directory Installation wizard does not automatically add a reverse lookup zone and PTR resource records, because it is possible that another server, such as the parent server, controls the reverse lookup zone.
For information about any of the IP addressing concepts discussed in the following sections, see "Introduction to TCP/IP" in this book.To determine where to place your reverse lookup zones, first gather a list of all the subnets in your network, and then examine the class (A, B, or C) and type (class-based or subnetted) of each subnet.To simplify administration, create as few reverse lookup zones as possible.For example, if you have only one class C network identifier (even if you have subnetted your network), it is simplest to organize your reverse lookup zones along class C boundaries.You can add the reverse lookup zone and all the PTR resource records on an existing DNS server on your network.
