When a DHCP server registers and updates DNS pointer (PTR) and address (A) resource records on behalf of its DHCP-enabled clients, it uses the information contained within an additional DHCP option: the Client FQDN option (option 81), which permits a client to provide its FQDN and any instructions to the DHCP server that is used to process DNS dynamic updates on its behalf.The following reasons or events can trigger a dynamic update: When one of these events triggers a dynamic update, the DNS Client service (not the DHCP Client service) sends updates.Hi, In short, I'm hoping for some reason behind DDNS not updating PTR records when a host changes IPs.It suggests in DDNS and infoblox documentation that PTR records should by dynamically updated.The reverse lookup zone exists, and I can add entries to it manually, but it doesn't automatically populate.Dynamic updates are enabled for both the forward and reverse zones. This could be due to a couple of different things: 1) Are your clients obtaining IPs via a Windows DHCP Server?This association, or mapping, of an IP address to a domain name requires that a change in either the address or the name necessitates an update of the information in DNS.

You can approach this by manually forcing the clients to check in.DNS servers provide domain name resolution for network resources.They associate the TCP/IP address assigned by DHCP to a client with its fully qualified domain name (FQDN).The DNS Client service performs this function for all network connections on the client, including any that are not configured to use DHCP.When a qualified DNS client (such as a computer running Windows XP Professional or Windows Vista®) issues an update, DHCP servers running Windows Server 2008 process the update to determine in which of three ways the server will initiate updates on behalf of the client: The ability to register both A and PTR resource records enables a DHCP server to act as a proxy for clients running other operating systems, such as Microsoft Windows Millennium Edition, or Windows 98, for the purpose of DNS dynamic update registration.
