Why does NetworkChange.NetworkAddressChanged keep getting raised?

Question

I am running .NET 7 on Linux. I tried get network change information with the following code, but I keep getting the event, even though the computer is constantly on, and it is a wired Ethernet. The addresses seem the same. Then, why is "network address change" keep happening?

Code

System.Net.NetworkInformation.NetworkChange.NetworkAddressChanged += (sender, eventArgs) =>
{
    NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
    foreach(NetworkInterface n in adapters)
    {
        PrintLog($"   {n.Name} is {n.OperationalStatus}. Desc:{n.GetIPProperties().UnicastAddresses.First().Address.ToString()}");
    }
