Up until very recently my IPV6 has worked well with Cloudflare DNS.
Last few days it simply doesn’t work and nothing has changed here - same firmware etc.
I’ve done the usual things like power cycle hardware in the proper sequence etc.
My home network is a Netgear Orbi RBK53 (3 units). MY router is an Arris SB8200 Docsis 3.1 unit.
In my router setup page for DNS it advises that it’s IPV6 address is not available on the WAN.
When I try to test (various IPV6 test sites) indeed it does not work, but says that my ISP supports IPV6 - I know this because it has worked for months.
Comcast tech support are of no help, the usual blame diverted to my router. Of course!
I’m attaching images of my IPV6 DNS settings in router and the errors from just one of the IPV6 test sites (but they all say it’s not working)
I’m hoping someone can help.
