And I tested again on master branch&commit id 7a992aeb(jira GH-700), it is fine.

Tried this with latest net branch (commit 85103e15de3fac) and with qemu but using different IP address space (192.0.2/24). I found no issues.

• Tested with A101/ENC over IPv4 and it works fine.
• Tested again now over IPv6 and it works fine also.

So, I guess there is a configuration issue from your side.

BTW, about the dns_client on qemu, I see the command ($ ip addr add 192.0.2.2/24 dev tap0) in README.rst file. But in the prj_qemu_x86.conf:CONFIG_NET_SAMPLES_MY_IPV4_ADDR="192.168.1.101" CONFIG_NET_SAMPLES_PEER_IPV4_ADDR="192.168.1.10". And when run 'loop_socat.sh' and 'loop-slip-tap.sh', the ipv4 address of tap0 is set to 192.0.2.2/24 automatically.

That's right, at some point the prj for qemu must be updated (again), Thanks.
