 By default, Windows computers that are statically configured for TCP/IP try to dynamically register host address (A) and pointer (PTR) resource records for IP addresses that are configured and used by their installed network connections. By default, all computer register records are based on the full computer name.

     For standard primary zones, the primary server, or owner, that is returned in the SOA query response is fixed and static. The primary server name always matches the exact DNS name as that name is displayed in the SOA resource record that is stored with the zone. However, if the zone that is being updated is directory-integrated, any DNS server that is loading the zone can respond and dynamically insert its own name as the primary server of the zone in the SOA query response.

-Dynamic updates are sent or refreshed periodically. By default, computers send an update every twenty-four hours.

Updates that cause actual zone changes or increased zone transfers occur only if names or addresses actually change.

-When the DHCP Client service registers A and PTR resource records for a Windows-based computer, the client uses a default caching time-to-live (TTL) value of 15 minutes for host records. This value determines how long other DNS servers and clients cache a computer's records when they are included in a query response.
