Description
The ip-assign-tracker script is designed to monitor and record changes to a system’s IP addresses. This can happen due to DHCP lease renewals, network reconfiguration, roaming between networks, or intentional static IP changes. The script listens for events triggered by the operating system or polls interfaces at regular intervals.
Every time an IP address changes, the script logs the old and new IP addresses, the associated interface (e.g., eth0, wlan1), and a timestamp. This is invaluable in environments where IP addresses are dynamic or where tracing device behavior across subnets is necessary.
The script is especially useful in mobile environments (like laptops or tablets moving across networks) or in virtualized systems where interfaces are dynamically reassigned. It’s also crucial in environments where static IP assignments are critical and any unauthorized change needs to be flagged.
Some advanced versions of this script can send notifications when an IP change occurs, post events to webhooks, or update a central logging server. It’s often used in combination with asset-tracking systems or security audits to ensure consistency in device identity.

“This IP assignment tracker is exactly what I needed! As a solo developer managing a complex network, keeping tabs on IP address changes was a constant headache. This tool provides real-time monitoring and clear, timestamped logs, making it incredibly easy to diagnose connectivity issues and identify unauthorized changes. The alert feature is particularly helpful, allowing me to react quickly to unexpected events. It’s streamlined my workflow significantly and given me much-needed peace of mind.”

“This file has been incredibly useful for tracking IP address changes on my network. The real-time monitoring and alerting features are fantastic, allowing me to quickly identify and address unexpected changes. The timestamped logs per interface provide valuable insights into network behavior, especially with DHCP lease renewals. I especially appreciate the flexibility of using either syslog or local log output. It’s a great tool for anyone managing a dynamic network or dealing with mobile devices.”

“This ip-assign-tracker has been an absolute boon for my dynamic network troubleshooting. It’s incredibly useful to get real-time logs of IP address changes, especially with mobile devices constantly connecting and disconnecting. The ability to monitor DHCP lease renewals and static reconfigurations, along with the alerting feature, has already saved me countless hours of diagnostic work. Simple to set up and the logging options are fantastic.”
