Hi folks,
busy days after upgrading to 19.07.7.
Almost everything is starting to work fine now, but I've observed that OpenWRT dnsmasq stops resolving a hostname with IPV6-only DNS authoritative domain server. Lets take a look:
root@murguisrouter:~# nslookup ds.v6ns.test-ipv6.arauc.br
;; connection timed out; no servers could be reached
root@murguisrouter:~#
Changing to another server (Google DNS, for example) works fine (IPv4 and 6 too):
root@murguisrouter:~# nslookup ds.v6ns.test-ipv6.arauc.br 8.8.8.8
Server: 8.8.8.8
Address: 8.8.8.8#53
Name: ds.v6ns.test-ipv6.arauc.br
Address 1: 200.238.130.45
Address 2: 2801:82:0:6::45
root@murguisrouter:~# nslookup ds.v6ns.test-ipv6.arauc.br 2001:4860:4860::8888
Server: 2001:4860:4860::8888
Address: 2001:4860:4860::8888#53
Name: ds.v6ns.test-ipv6.arauc.br
Address 1: 200.238.130.45
Address 2: 2801:82:0:6::45
root@murguisrouter:~#
It seems that IPv6 connection works:
root@murguisrouter:/etc/config# ping6 -c 2 ipv6.google.com
PING ipv6.google.com (2800:3f0:4001:817::200e): 56 data bytes
