The first step is to identify the affected systems. But finding an IP address conflict is not always easy. When a conflict is intermittent, it can be difficult to identify affected systems using PING and ARP utilities. This is where SolarWinds IP Control Bundle can help.
SolarWinds IP Control Bundle actively identifies IP conflicts and tells you when systems are contending for the same IP address. These alerts are organized by subnet and clearly identify the affected systems. The alert will even identify device types and show you which switch and switch port these systems are connected to. This one resource alone will save you valuable troubleshooting time.
Next, you can begin troubleshooting an IP conflict from the alert. One click will take you into the IP address conflict details. Here you’ll see more information on the cause of the conflict and specific details on the endpoints involved. To restore service fast, you can isolate the culprit from the network by performing a remote port shutdown. This will give you time to find an available IP address and to configure the DHCP and DNS systems for that host.
The final step in this example is to reconfigure the IP settings on the system causing the IP conflict. Now that the system type and location are known, it’s easy to make the needed changes. First, find an available IP address and make the needed DNS and DHCP configuration entries. Then update the server configuration.
