DNS forward lookup zone - records accuracy
Posted on 2013-12-17
I have a 3-part (hopefully simple) question about my forward lookup zone. I'm using 2 DCs (Server2008 R2), in a single domain environment. The functional level is Server2003.
1. When I try to find an "available" IP address, for a static dev server, or whatever, the process is extremely tedious because my forward lookup zones don't include DHCP leases that aren't associated with FQDNs. This means i have to ping addresses over and over until I find one that seems available. Is there a way to see all used IPs?
2. While pinging, I get responses from FQDNs that aren't listed in my forward lookup zone. Is this related to the secure/non-secure updates checkbox?
3. While perusing the foward lookup zone, I see entries in there from ages ago. Yet i have scavenging set to 8 days. I've had this problem for several years now... I thought that upgrading my DC functional level would solve this, but no success... Any ideas?
