I don't know anything about Infoblox, but be aware that these concepts are Microsoft-specific and may simply not exist on the Infoblox platform. ISC DHCP and BIND don't have the DHCP client update DNS, the way Microsoft does. Instead, the DHCP server submits DNS updates. This has a number of advantages, including the fact that you simply don't need refresh, scavenging, client authentication, DHCP option 81, name protection, etc., etc., etc. DNS gets updated as DHCP leases are requested and expire, by the authoritative DHCP server. The one big drawback is non-DHCP nodes don't get DNS updates. (I expect the thinking at ISC is that nodes using manual IP addressing would prolly have manually configured DNS records as well.) If Infoblox works the same way, your questions simply don't apply. (Granted, they should know this.) -- Ben
