    Hi, I have a 2003 AD domain, with AD-integrated DNS and DHCP. I recently
    added a new subnet as we were topping out the old one, call them, and the new one is
    I created a new DHCP scope (not with a superscope) to allocate addresses
    in the new subnet, which works fine.
    Issue 1: However, it seems that the DHCP-allocated addresses in the new
    subnet do not appear in the reverse zone,DNS, though fixed addresses,
    with their manually created A records, do.
    Issue 2: I created a Reverse Zone in the DNS for the but
    no PTRs showed up. When I created A records with, they
    showed up only when I created another reverse zone of 23.168.192. Why is
    that? Shouldn't it recognize that the 20 and 23 is the same subnet?

    Any help afforded will be appreciated.
