I didn't have IPv6 available from the sole (land-based) ISP who offered service at my last house, Altice USA (Suddenlink/Optimum). I moved away about 13 months ago. (Worse yet their modem/router did RAs or whatever but there was no connectivity out) The past 10 years of IPv6 have been largely uneventful for me: it just doesn't work. |

IPv6 worked "too well" for me: a while ago I was web surfing I had all those little Facebook icons show up that were served from their web site, probably dropping cookies on my system. I didn't want that so I put FB's domain in my hosts(5) file so that it go to "0.0.0.0": the little icons went away.
Then suddenly they appeared. And I checked hosts to make sure things were still there, and I did web browser debugging to see if things changed in the HTML.
And then I remembered that my ISP had activated IPv6, and so the icons were coming from FB's IPv6 address. Once I added "::1" for FB in my hosts file the icons disappeared again.
