What is addressMapLastChange?
This timestamp marks when this address mapping was first created or when its physical address last changed. Frequent updates signal a duplicate address problem or address takeover; stable values mean stable mapping. If the LastChange time stays old but suddenly updates, someone may have unplugged the original device and plugged in a replacement at that IP.
