Absolutely. I used to have a lot of weird IPv6 issues in my home network I didn't understand. ChatGPT helped me to dump some traffic with tcpdump and explained what was happening on the network.

In the process it helped me to learn many details about RA and NDP (Router Advertisments/Neighbor Discovery Protocol, which mostly replace DHCP and ARP from IPv4).

It made me realize that my WiFi mesh routers do quite a lot of things to prevent broadcast loops on the network, and that all my weird issues could be attributed to one cheap mesh repeater. So I replaced it and now everything works like a charm.

I had this setup for 5 years and was never able to figure out what was going on there, although I really tried.
