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)?
