Add a Reverse Lookup Zone on a DNS Server – Windows Server 2008 R2

Reverse lookup zones support the resolution of IP addresses to host names. Although they are optional in most networks, reverse lookup zones might be necessary for certain secure applications that require the validation of IP addresses.

Although adding a reverse lookup zone in Domain Name System (DNS) is similar in many respects to creating a forward lookup zone, there are some important differences:

  • One important difference is that a reverse lookup zone is always a subdomain of either the domain (which supports reverse lookups for IP version 4 (IPv4) addresses) or the domain (which supports reverse lookups for IP version 6 (IPv6) addresses).
  • Another important difference is that the subdomain name is constructed from the address of the subnet that contains the range of addresses for which the reverse lookup zone is responsible. When you create the reverse lookup zone, you specify this address in a particular format so that it can be recognized by the DNS server as pertaining to the address in a reverse lookup query.
