The probe in my garage (literally) has been running since 2015. I haven’t spent much time thinking or working with it, so forgive this potentially dumb question. I looked it up on the atlas.ripe.net <http://atlas.ripe.net/> site. Besides the being a note about lacking a USB stick (wasn’t aware of that), I see that the host had a IPv6 address until July and since then a series of IPv4 addresses. I can’t recall a major network event around then (the probe was offline 18 1/2 hours. Is there a reason I don’t have a v6 address now? Should I have one (as in, is something wrong to make it fail back to v4)? I did have a network overhaul in September (off line for 15h 20m). I had to “fix” IPv6 in the house then but got it working with the new CPE device. Checking, when I go to ripe.net’s webpage, it shows me coming over IPv6. FWIW, my house is a simple cable-company-as-ISP home set up, consumer-grade v4 and v6. (I try to leave work at work, if you know what I mean.) …meanwhile, I’m going to see if there is a USB stick in the house. (Maybe it’s near the book of postage stamps, DVD’s, and cassette tapes.) Ed
