# Configuration file for dnsmasq.
#
# Format is one option per line, legal options are the same
# as the long options legal on the command line. See
# "/usr/sbin/dnsmasq --help" or "man 8 dnsmasq" for details.

# Change these lines if you want dnsmasq to serve MX records.
# Only one of mx-host and mx-target need be set, the other defaults
# to the name of the host  running dnsmasq.
#mx-host=
#mx-target=
#selfmx
#localmx

# The following two options make you a better netizen, since they 
# tell dnsmasq to filter out queries which the public DNS cannot
# answer, and which load the servers (especially the root servers) 
# uneccessarily. If you have a dial-on-demand link they also stop
# these requests from bringing up the link uneccessarily.

# Never forward plain names (with a dot or domain part)
domain-needed
# Never forward addresses in the non-routed address spaces.
bogus-priv


# Uncomment this to filter useless windows-originated DNS requests
# which can trigger dial-on-demand links needlessly.
# Note that (amongst other things) this blocks all SRV requests, 
# so don't use it if you use eg Kerberos.
#filterwin2k

# Change this line if you want dns to get its upstream servers from
# somewhere other that /etc/resolv.conf 
#resolv-file=

# By  default,  dnsmasq  will  send queries to any of the upstream
# servers it knows about and tries to favour servers to are  known
# to  be  up.  Uncommenting this forces dnsmasq to try each query
# with  each  server  strictly  in  the  order  they   appear   in
# /etc/resolv.conf
#strict-order

# If you don't want dnsmasq to read /etc/resolv.conf or any other
# file, getting its servers for this file instead (see below), then
# uncomment this
#no-resolv

# If you don't want dnsmasq to poll /etc/resolv.conf or other resolv
# files for changes and re-read them then uncomment this.
#no-poll

# Add other name servers here, with domain specs if they are for 
# non-public domains.
#server=/localnet/192.168.0.1

# Add local-only domains here, queries in these domains are answered
# from /etc/hosts or DHCP only.
#local=/localnet/

# Add domains which you want to force to an IP address here.
# The example below send any host in doubleclick.net to a local
# webserver.
#address=/doubleclick.net/127.0.0.1

# You no longer (as of version 1.7) need to set these to enable 
# dnsmasq to read /etc/ppp/resolv.conf since dnsmasq now uses the
# "dip" group to achieve this.
#user=
#group=

# If you want dnsmasq to listen for requests only on specified interfaces
# (and the loopback) give the name of the interface (eg eth0) here. 
# Repeat the line for more than one interface.
#interface=
# Or you can specify which interface _not_ to listen on
#except-interface=
# Or which to listen on by address (remember to include 127.0.0.1 if
# you use this.)
#listen-address=127.0.0.1

# On systems which support it, dnsmasq binds the wildcard address,
# even when it is listening on only some interfaces. It then discards
# requests that it shouldn't reply to. This has the advantage of 
# working even when interfaces come and go and change address. If you
# want dnsmasq to really bind only the interfaces it is listening on,
# uncomment this option. About the only time you may need this is when 
# running another nameserver on the same machine.
#bind-interfaces 

# If you don't want dnsmasq to read /etc/hosts, uncomment the
# following line.
#no-hosts
# or if you want it to read another file, as well as /etc/hosts, use
# this.
#addn-hosts=/etc/banner_add_hosts

# Set this (and domain: see below) if you want to have a domain
# automatically added to simple names in a hosts-file.
#expand-hosts

# Set the domain for dnsmasq. this is optional, but if it is set, it
# does the following things.
# 1) Allows DHCP hosts to have fully qualified domain names, as long
#     as the domain part matches this setting.
# 2) Sets the "domain" DHCP option thereby potentially setting the
#    domain of all systems configured by DHCP
# 3) Provides the domain part for "expand-hosts"
#domain=thekelleys.org.uk
  
# Uncomment this to enable the integrated DHCP server, you need
# to supply the range of addresses available for lease and optionally 
# a lease time. If you have more than one network, you will need to
# repeat this for each network on which you want to supply DHCP
# service.
#dhcp-range=192.168.0.50,192.168.0.150,12h
#dhcp-range=10.0.0.10,10.0.0.200,2h

# This is an example of a DHCP range where the netmask is given. This
# is needed for networks we reach the dnsmasq DHCP server via a relay 
# agent. If you don't know what a DHCP relay agent is, you probably
# don't need to worry about this.
#dhcp-range=192.168.0.50,192.168.0.150,255.255.255.0,12h
