Dhcp not updating dns ptr records

This action then causes the DHCP server to submit an update request to its configured DNS server on behalf of the client.

Domain Name System (DNS) client computers can use dynamic update to register and dynamically update their resource records with a DNS server whenever changes occur.

By default, the DNS Client service dynamically updates host (A) resource records in DNS when the service is configured for TCP/IP.

Dhcp not updating dns ptr records

Would like to see about getting DHCP configured on a Cisco switch to auto-register the computers hostname with a MS DNS server.

Had to troubleshoot a workstation hogging bandwidth.

Those records have an ACL on them to stop registered records from being hijacked by other hosts.

When DHCP is used to allocate IP addresses, the default configuration is shown below—which tells the DHCP server to register records in DNS on behalf of clients only if requested to do so by the client or if the client is unable to dynamically register (e.g., Windows NT 4.0).

It suggests in DDNS and infoblox documentation that PTR records should by dynamically updated.
