Windows dns not updating from dhcp
Similarly, steps 6-8 update the inverse mapping from the IP address to the domain name (type PTR RR).In the correct setup, the LDNS should point the DHCP client to a domain name server (could be itself) inside the internal network.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.Most home users who use DSL/Cable routers as DHCP/NAT servers to facilitate multiple host connections to the Internet should turn off dynamic DNS updates.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.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.Both DHCP clients and servers can generate DNS updates.
This means that any authenticated user or computer can create a new object in the zone.
For the DNS update feature to work, the DNS server, the DHCP server, and the DHCP client must be set up correctly.
In addition, the requested host name must not be in use by another system in the domain.
``So what if my host leaks a few packets to the global Internet? '' The reason is that inconsistent configuration between your home hosts and your local DNS servers can, and often does, cause leakage of DNS updates for private IP addresses to the global Internet.
This leakage causes the following problems: Unfortunately, most users have no knowledge of their own misbehaving hosts broadcasting private information to the world.
