Just found out I have 2 external IP addresses

I was trying to troubleshoot a home networking issue, and I plugged my laptop's Ethernet cable into the second bridge port. I thought it would recognize that the device wasn't a router and assign a local IP address behind a firewall. Nope. Windows was assigned an external one.
I suppose now I have the option to have my self-hosted services hosted on a different IP address.
Kinda scary that my isp just allows unknowing customers to expose their equipment to the net
If you're wondering, yes, I did change the IP addresses before posting this

  • You plugged into a bridge port, and surprised it's bridging your traffic?

    Many isps will give 2 ips. Otherwise when you move to a new device, you would have to call them to unregister your first one.

    • im just surprised that there weren't any checks that could have prevented an unknowing customer from exposing their devices. Nothing on the fiber modem was labeled, so im kinda worried how many things could be potentially exposed

      • They don't have any way to know if it's a router or a laptop plugged in.
