Hi,

The only thing what you should do install the package with apt and copy the config file. in the example. I don’t want to explain it deeper, everything is commented:

apt-get install dnsmasq

Open the /etc/dnsmasq.conf file and paste it:

# Add interfaces listen to
listen-address=127.0.0.1
listen-address=172.17.9.254

## Global settings
expand-hosts   # add domain names to hostfile
bind-interfaces
# blocks probe-machines attack
stop-dns-rebind
rebind-localhost-ok
resolv-file=/etc/resolv.conf
no-poll    # prevent dnsmasq from polling the .resolv. file for changes
no-hosts   # Don't allow to resolv from /etc/hosts

## Domain options
domain=example.com
expand-hosts
local=/example.com/
domain-needed   # Never forward plain names
bogus-priv              # Never forward addresses in the non-routed address spaces.
all-servers  # dnsmaq will send request to all server, and use the first reply

cache-size=2000   # DNS cache size
neg-ttl=1800    # store the negatice replies until 30min


## Logging
log-facility=/var/log/dnsmasq.log
