Yes, but my dnscache is complemented by tinydns for providing local
DNS (internal use, for my LAN only).

dnscache is not intercepting anything. Check the logs, dnscache has its
own logs -- try this in a separate console/xterm/shell:

tail -f /service/dnscache/log/main/current | tai64nlocal

Check your /etc/syslog.conf to figure where your daemon logs and news
logs go. Mind the time stamps in the log.

Presumably dnscache cannot resolve the name of your client and this
process is slow. Try putting your local clients either into tinydns or,
easier, into /etc/hosts and giving /etc/hosts precedence over
DNS. (/etc/nsswitch.conf: "hosts: files dns")

You cannot run two dns listeners (pdnsd and dnscache) on the same IP at
the same time. You can however redirect certain domains from dnscache to
a certain different IP. I am redirecting domain.example.net and
0.168.192.in-addr.arpa.
