It is important to understand how clients update their DNS records dynamically to prevent issues where the process fails due to poor management of your DNS zones and records.Many DNS administrators find that the Dynamic DNS update process, and aging/scavenging processes may be difficult to understand and manage correctly.

This behavior controls and manages DNS and Active Directory replication (for AD Integrated Zones).``So what if my host leaks a few packets to the global Internet? '' The reason is that inconsistent configuration between your home hosts and your local DNS servers can, and often does, cause leakage of DNS updates for private IP addresses to the global Internet.This leakage causes the following problems: Unfortunately, most users have no knowledge of their own misbehaving hosts broadcasting private information to the world.Microsoft Windows operating systems support a feature that dynamically updates the mappings of domain names to associated IP addresses assigned to hosts by DHCP servers.This automatic updating, called Dynamic DNS Updates service, reduces the administrative overhead associated with manually administering DNS records of network hosts.In the case of using the DHCP service to register client's DNS records, you need to add the DHCP server's computer account to the DNSUpdate Proxy Security group and set the appropriate settings on the DHCP server's properties.

In this case, the DNS client registers the host (A) resource record.

Only if you know with certainty that the updates get sent only to a local DNS server should you run the Dynamic DNS Updates service.

Most home users who use DSL/Cable routers as DHCP/NAT servers to facilitate multiple host connections to the Internet should turn off dynamic DNS 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.

Hopefully, the information in this article will help you understand the relationship between DNS security and record updates to prevent issues such as clients NOT being able to update their DNS records, or DNS records being scavenged for legitimate domain computers.
