I think you have failed to show us what is in /etc/resolv.conf on the
machine, which is running host command.
unless listen-address or interface is specified, it should listen on all
interfaces.
Try using host -v jacquibennett.com, it might provide more details what
exactly has timed out.
If unsure what is host contacting, try separate queries to server
specified explicitly:
- host -v jacquibennett.com 127.0.0.1
- host -v jacquibennett.com 127.0.1.1
That might provide hints what is failing and what is working.

I use dnsmasq on a number of, mostly Ubuntu, home systems. One system
at 192.168.1.2 acts as the DNS server for my LAN, then there are
several 'client' systems that just use dnsmasq as a caching DNS server
for their own lookups.
I *suspect* I have a problem with looking up names via the local
dnsmasq because it is listening only on 127.0.1.1 and the request is
on 127.0.0.1#53.
for example a 'host'command on my laptop returns:-
chris$ host jacquibennett.com
;; communications error to 127.0.0.1#53: timed out
jacquibennett.com has address 153.92.6.161
jacquibennett.com has IPv6 address 2a02:4780:a:1080:0:174b:7855:7
jacquibennett.com mail is handled by 5 mx1.hostinger.com.
jacquibennett.com mail is handled by 10 mx2.hostinger.com.
But dnsmasq is running on the laptop:-
dnsmasq 7443 1 0 09:27 ?00:00:01 /usr/sbin/dnsmasq -x
/run/dnsmasq/dnsmasq.pid -u dnsmasq -7
/etc/dnsmasq.d,.dpkg-dist,.dpkg-old,.dpkg-new --local-service
--trust-anchor=.,20326,8,2,e06d44b80b8f1d39a95c0b0d7c65d08458e880409bbc683457104237c7f8ec8d
The dnsmasq configuration file on the laptop (and other client
systems) is almost non-existent, it's just:-
resolv-file=/run/NetworkManager/no-stub-resolv.conf
... /run/NetworkManager/no-stub-resolv.conf is:-
# Generated by NetworkManager
search zbmc.eu
nameserver 192.168.1.2
... and in /etc/dnsmasq.d I just have a blacklist file with lots of
address= entries, but that's all. The /etc/default/dnsmasq
file just has:-
ENABLED=1
CONFIG_DIR=/etc/dnsmasq.d,.dpkg-dist,.dpkg-old,.dpkg-new
So why do I get that timeout error from the 'host' coommand? It's as
if dnsmasq on the local machine isn't listening on 127.0.0.1. Does it
only listen on 127.0.1.1 by default?
