Also, like a forward lookup zone, a reverse lookup zone can be integrated with Active Directory Domain Services (AD DS), and it can be mirrored by secondary and stub zones.You can also delegate a reverse lookup zone, and you can configure a reverse lookup zone to accept dynamic updates, which reduces the need to add and manage pointer (PTR) resource records directly.This type of query expects an IP address as the resource data for the answered response.
They associate the TCP/IP address assigned by DHCP to a client with its fully qualified domain name (FQDN).
This association, or mapping, of an IP address to a domain name requires that a change in either the address or the name necessitates an update of the information in DNS.
The following reasons or events can trigger a dynamic update: When one of these events triggers a dynamic update, the DNS Client service (not the DHCP Client service) sends updates.
The DNS Client service performs this function for all network connections on the client, including any that are not configured to use DHCP.
so i manually tried to add it using "ipconfig /registerdns". I was also reading something on scavenging, but that will only fix the old entries that will deleting but I'm not sure about actually getting the correct entries to begin with.
