I hope there was an IP address, which should have been one belonging to PIA and not the IP address of your home router.Is this a concern?
DNS Server. The load on Cloudflare (and other big DNS providers) is so great that 1.1.1.1 gets rerouted to whatever Cloudflare server(s) are nearest to you. I get 172.71.89.70 which is an Australian Cloudflare DNS server. So all as expected.
