Dynamic dns not updating

Clients with dynamically-set network connections (DHCP clients) will communicate with both the authoritative DNS server and the DHCP server for updating A and PTR records.

The DHCP client will communicate with the authoritative DNS server directly for updating its A record, but the DHCP server updates the DNS server with the client’s PTR record In some cases, a DHCP server may update a client's A record on its behalf, even if the client did not specifically request this.

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.

I have checked the event viewer logs for the DHCP and DNS server but nothing is present?

Some customers have reported issues with Microsoft Dynamic Updates after installing virtual appliances (VAs) in their environment or installing the Umbrella Roaming Client on some machines.

You likely had no way of knowing there would be a problem until you received the notice in your Email.Please see For a DHCP client, when some particular action causes its IP address to change, such as a DHCP lease renewal, if the client supports it, it will send Client FQDN information (DHCP option 81 flags) to the DHCP server.The DHCP server will use this information, along with its dynamic update configuration, to determine whether or not the DHCP server will perform the PTR record update against the authoritative DNS server on behalf of the client, or if the client will perform the PTR update against the authoritative DNS server on its own. The first step of this process still involves the client machine sending an SOA-type query to the configured DNS server.The client then receives information from the authoritative DNS server indicating which server will be processing the update.The roaming client is lightweight software installed on Windows machines which takes in the client’s DNS queries and conditionally forwards them to Umbrella anycast resolvers.The roaming client forwards DNS queries listed in Internal Domains to the local DNS servers on the network.As long as the Internal Domains are correctly populated, then any SOA queries for any internal-facing domains will be sent to the local DNS server."I want to send updates myself via TSIG rather than install software." Many hardware devices, such as DVRs, webcams, routers, etc, have built in update clients.Unfortunately, as they are all third-party products, you’ll need to contact the manufacturer for support with the device. If your host was blocked for abuse, it probably wasn’t something that you did intentionally.From there, the client continues communicating with the primary DNS server that accepted the A record update.Please see For a static client, the client will communicate directly with the authoritative DNS server to update its PTR record.
