I am behind a Calix router at home for my ISP and 1.1.1.1 goes to my router and not any further. When I enter the IP into my browser, it opens the login page for my router. So it appears 1.1.1.1 is used as a loopback in my Calix router.
1.0.0.1 goes to the proper place fine. On Sun, Apr 1, 2018 at 3:59 PM, Jeremy L.
