Dear Dmitry,

Apple is evil :-)

We done extensive testing with linux, android and windows machines, but been not able to make it work with IOS.

We added fec0:0:0:ffff:[1,2,3] purely for backward compability, because windows machines use them by default.

This should not prevent connectivity.

Espesially for you we have changed RA to provide global v6 DNS address, now it should work OK.

Please check.

Best regards
Levon Avagyan

I have tried it first thing - both from iPhone iOS (9.3.5 and 10.0.1) and MacOS (10.11.6) - IPv6 address is given,
but of course IPv4 addresses are auto-assigned from link-local range, 169.254.0.0/16, however, DNS address shows as fec0:0:0:ffff:1 which does not work.

This address is part of IETF draft (expired in 2002) about DNS discovery on IPv6. It should not be used.

You can find me and I would show you how things don’t work :)
