Dhcp address not updating in dns
I have been looking at the Cisco docs for getting this to work but nothing yet.Would appreciate any pointers on getting this to work.
The Oracle Solaris DHCP server does not perform DNS updates for IP addresses that the server does not manage.Problem: Client accepted an offer from a DHCP server that does not issue DNS updates.Solution: If two DHCP servers are available to the client, the servers should both be configured to provide DNS updates.Have you ticked the dox in DNS properties on the server role that is listed as "Dynamically update DNS A and PTR records for DHCP client that do not request updated (for example, clients running Windows NT 4.0)?The following list includes describes possible problems a client might have in getting its requested hostname, and suggested solutions.See Enabling Dynamic DNS Updates by a DHCP Server for information about configuring the DHCP server and the DNS server.
To determine whether the DHCP server is configured to provide DNS updates: is option code 12. For an Oracle Solaris client, see How to Enable an Oracle Solaris DHCPv4 Client to Request a Specific Host Name Problem: DHCP server that makes an address offer to the client does not know the client's DNS domain.
The first is "dynamic DNS updating" which refers to systems that are used to update traditional DNS records without manual editing.
These mechanisms are explained in RFC 2136, and use the TSIG mechanism to provide security.
Had to troubleshoot a workstation hogging bandwidth.
Using Netflow, I could see the ip address of the offender but couldnt see the hostname of the computer/workstation that was the offender.
