> I recently switched ISP to one that supports IPv6 and I have had nothing but problems. I was previously with an ISP that support IPv6 and had zero problems. In fact IPv6 worked "too well" at one point: I had put "facebook.com" in my /etc/hosts file pointing to 0.0.0.0 at one point to reduce tracking. I then noticed I got the little FB icons again at some point and couldn't figure out why things were 'broken' (i.e., not blocking). Turned out that after IPv6 was enabled I had to add ::1. That blocked FB again. IPv6 made connectivity to FB work again.
