All, This isn't terribly important, but I'm still curious about it, and after perusing RFC 4701 I still have a question about it. I was adding a host statically to DNS, and noticed that only a few of my hosts (some with static or DHCP reserved addresses, some not) have DHCID RRs. The biggest portion of them were printers with DHCP reservations, but there are also iOS and Android devices, and a *nix workstation or two, with dynamically assigned addresses - but no Windows machines, workstations or servers. Any ideas why that differentiation? Kurt List info: http://www.activedir.org/List.aspx

Windows "machines" automatically update their own host records without any help from DHCP even if they get their IP address from DHCP. Non-Windows hosts don't have the ability to do this so DHCP adds the host record for them if the default options are left in place. See http://technet.microsoft.com/en-us/library/cc787034(v=WS.10).aspx for more info.
