Dhcp address not updating in dns

This leakage causes the following problems: Unfortunately, most users have no knowledge of their own misbehaving hosts broadcasting private information to the world.

The default configuration not only wastes global Internet resources but also introduces a multitude of security, privacy and intellectual property concerns.

The following list illustrates a typical example of how a private DNS update leaks out to the global Internet. The DHCP client first sends a query to its local domain name server (LDNS) and asks for the authoritative server for the zone of its domain name (step 3).For Linux or Free BSD systems that use ISC's DHCP client and server software, the dynamic DNS update feature gets set to off by default and requires manual intervention to turn on the service.Both DHCP clients and servers can generate DNS updates.I even went to the workstation, did a ipconfig /release and renew then a flushdns and registerdns.That workstation has 192.168.1.80 now but in dhcp and dns its still showing 192.168.1.32 from 2 months ago and its not updating.
