Ed, assuming Cox is your ISP this page has info from them regarding IPV6: https://www.cox.com/residential/support/ip-version-6.html

They say that as long as your modem and router are capable, you should get IPV4 and IPV6 addresses at the same time. Your router, firewall, DHCP and DNS are all a big part of that. Each one of those has to be capable and have it enabled for the Atlas device to get an IPV6 address. If they are, then Cox would be the next one to contact.

General question…

My probe was doing IPv6 until 15 July 2021 but not it is not. Is there any way to discover why it is no longer IPv6’ing?

I did change my ISP connection equipment about that time, so something did change on my end.

But IPv6 works for other devices. When I go to www.ripe.net it tells me I came from an IPv6 address.

The device has been pretty steady - 99.71% the last week, 99.91% for the last month (30days). It was off-line 29 minutes earlier today (the notice made me think to look), but never off line more than 10 minutes since mid-July. There’s one stretch of 34d+ of continuous uptime. Run-of-the-mill home connection via a cableTV company.

Is there anyway to ask a probe why it doesn’t have an IPv6 address (via DHCP)?
