I am trying to confirm what that statement means based on the scavenging video https://www.infoblox.com/resources/videos/infoblox-dns-scavenging-managing-dns-records-todays-dynami...
The paragraph under the video states DHCP Leases expires and Infoblox deletes the DNS record automatically. The video states around 20 sec in that in a pure Infoblox world, DNS scavenging is not necessary. The Infoblox Grid tracks the life cylce of the leases and their associated DNS records.
As an example, a user disconnected a Windows/Mac laptop without shutting down and did not turn it back on again. I want to confirm that after the DHCP lease expires, DHCP would release the IPv4 address and then notify DNS that it can delete the A record for the computername. Is that correct? If so, is this configured by default when DDNS is setup or is there some other configuration that is needed? I am more focused on the improperly shutdown devices that the ones that shut down because in know DHCP can be set with option 43 to release the IP on shutdown.
I am very new to Infoblox so sorry for the basic question and thank you in advance!
