I have a simple setup:
internet <-- ISP modem (bridge mode) <-- openWrt router (router mode)
I left the wifi open on the ISP modem, so I can connect to the internet via my openWrt router or ISP router.
When I go to this website to check my IPv4 and IPv6 address, I was surprised to see:
When connecting my client to the ISP modem, and then checking that website, I see NO IPv4 address and I see an IPv6 address. Before I connected my openWrt setup, I had both an IPv4 and IPv6 address. Does anyone have a guess why that is?
When connecting my client to the OpenWrt modem, and then checking that website, I see an IPv4 address and a DIFFERENT IPv6 address (different from the ISP modem). I am suprised by that, I was expecting the same. Does anyone have a guess on why that is?
