My desktop/server runs as a web server, it serves the domain zbmc.eu.
It's set up so that local client requests for web pages from zbmc.eu go
'out and back' as it were, this way I can be more certain that web pages
that work locally also work when accessed from outside.
However sometimes I notice long pauses when displaying web pages so, in
an attempt to diagnose this I have turned on DNS logging in dnsmasq
(which runs on another server on my LAN). Just now I saw this:-
Apr 8 16:40:56 dps dnsmasq[22279]: query[AAAA] zbmc.eu from 192.168.1.4
Apr 8 16:40:56 dps dnsmasq[22279]: forwarded zbmc.eu to 195.74.113.58
Apr 8 16:40:56 dps dnsmasq[22279]: forwarded zbmc.eu to 194.72.0.114
Apr 8 16:41:01 dps dnsmasq[22279]: query[AAAA] zbmc.eu.zbmc.eu from
192.168.1.4
Apr 8 16:41:01 dps dnsmasq[22279]: forwarded zbmc.eu.zbmc.eu to

Apr 8 16:41:01 dps dnsmasq[22279]: forwarded zbmc.eu.zbmc.eu to

Apr 8 16:41:01 dps dnsmasq[22279]: reply zbmc.eu.zbmc.eu is NXDOMAIN-IPv6
Apr 8 16:41:01 dps dnsmasq[22279]: query[A] zbmc.eu from 192.168.1.4
Apr 8 16:41:01 dps dnsmasq[22279]: forwarded zbmc.eu to 195.74.113.58
Apr 8 16:41:02 dps dnsmasq[22279]: reply zbmc.eu is 84.45.228.40
Apr 8 16:41:17 dps dnsmasq[22279]: query[A] info.gigaset.net from
192.168.1.129
Apr 8 16:41:17 dps dnsmasq[22279]: cached info.gigaset.net is
217.67.103.237
Those requests for zbmc.eu.zbmc.eu look a bit worrying! :-) Can
anyone suggest what I might have misconfigured such that it would do
this? I *think* the particular request(s) that caused this were to
display some DokuWiki pages, but I'm not absolutely certain. Is there
any other sort of logging I can turn on (in apache2 for example) which
might show me the cause?
