I assume you talk about a hardware probe (the behavior on software probes is out of control of ripe). Recognizing the new network takes a while. But in the end, I think it is a flaw of your router. It should withdraw the old prefix by using reasonable life times/ zero life times. Here is an example with a hw probe and ~daily reconnects. The measured disconnected time is between 2 and 5 minutes usually. I think that's ok. https://atlas.ripe.net/probes/53236/#tab-network Regards, Thomas
