That sounds like a provider problem with their configuration most likely. I run hundreds of 844E, 844Gs and have one at my house even, and it continues out fine for 1.1.1.1 when I was testing over the weekend with our config.

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.
