DNS replies oddness
Hi everybody,

I am running 3.16.1.0b01 and I noticed a couple of odd things about DNS replies.

1) 0.0.0.0 is returned as an answer:
% host K6LUD.local.mesh                                            
K6LUD.local.mesh has address 0.0.0.0
K6LUD.local.mesh has address 10.58.196.195

17:09:36.285729 IP 192.168.1.148.34185 > 192.168.1.2.53: 62407+ A? K6LUD.local.mesh. (34)
17:09:36.330527 IP 192.168.1.2.53 > 192.168.1.148.34185: 62407* 2/0/0 A 0.0.0.0, A 10.58.196.195 (66)

It does not seem to confuse my browser, but it seems it was confusing another old dnsmasq I was trying to use as forwarder.

2) my pc (Debian jessie) always issues both A and AAAA queries.
The default dnsmasq on the arend node answers to the A ones, but silently ignores the AAAA, causing log resolution times and timeouts.
I worked around it by installing dnsmasq-full. Now it forwards the AAAA request to the WAN DNS servers (not ideal), but at least replies to AAAA queries (with a NXDOMAIN).

Thanks,
Ludovico

Hi,
I noticed that the problem only happens when I am not connected to any other node.
As soon as I connect to another node (via tunnel, I do not have anoy other node over the air yet), the problems stops from happening.


I am attaching the support file downloaded while the problem is happening.

Thanks,
Ludovico

Thank you for the file.
Thank you for the file.

I can confirm I see the issue in the file you sent.  I'll take the files and see if I can duplicate and track down the cause.
