    Dynamic IP and releasing polling IP address?

    satcomtim

      Issue/Question: Is there a way, when the FQDN can't be resolved to release the polling IP?

       

      Have an issue when using Dynamic IP Addresses and not releasing the polling IP address.

       

      In our environment, systems come up and check an IP out from a Server (similar to but not DHCP) and then a DNS record is created. When the system goes down the IP is released and the DNS record is deleted.

       

      I can track nodes just fine by adding their FQDN. The issue is the node shows the polling IP and does not release this IP when the DNS is deleted. When the original FQDN comes back up, a topology change happens and the polling IP updates.

       

      The issue is the polling IP gets handed back out to another server, with a different FQDN, and NPM shows the original node as up even though it is not giving a false positive on status.

       

      Is there a way, when the FQDN can't be resolved to release the polling IP?
