Dhcp not updating a records in dns

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.Did you find something wrong with the information on this page?Please take a moment to report it to us so that we can continue to improve the quality of the information on this site. Recall that computer accounts are also security principals and therefore deleting the object and recreating the object results in a NEW object with a different SID.In other scenarios, when a change is made on the DHCP server such as configuring the DHCP service to update DNS records on behalf of the client, the DHCP server may not update a DNS record when the client registers a DNS record.``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.

This automatic updating, called Dynamic DNS Updates service, reduces the administrative overhead associated with manually administering DNS records of network hosts.

The default configuration not only wastes global Internet resources but also introduces a multitude of security, privacy and intellectual property concerns.

Leakage of private DNS updates is caused by inconsistent configuration between DNS servers and DHCP client/server entities.

During the Refresh interval, which is 7 days by default, the client's DNS time stamp is updated.

During the Scavenging interval, old DNS resource records are automatically deleted.
