You do not need to disable dynamic DNS updates if: However, if you have configured your host to act as a DHCP client/server and you make use of the private IP address space (including 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16) specified in RFC1918, you should turn off the dynamic DNS update feature.Only if you know with certainty that the updates get sent only to a local DNS server should you run the Dynamic DNS Updates service.For more details about a particular feature or functionality and its replacement, see the documentation for that feature. If you need to control specific security settings, you can use either Group Policy or Microsoft Security Compliance Manager.The following features and functionalities have been removed from this release of Windows Server 2016. The opt-in components that manage participation in the Customer Experience Improvement Program have been removed.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.This automatic updating, called Dynamic DNS Updates service, reduces the administrative overhead associated with manually administering DNS records of network hosts.While this service can reduce administrative overhead, it also can, and does, have deleterious effects on the larger Internet by leaking traffic regarding private IP addresses that should never leave the local area network.
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).
