 # 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.

 # Listen on this specific port instead of the standard DNS port
 # (53). Setting this to zero completely disables DNS function,
 # leaving only DHCP and/or TFTP.
 #port=5353

 # 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)
 # unnecessarily. If you have a dial-on-demand link they also stop
 # these requests from bringing up the link unnecessarily.

 # Never forward plain names (without a dot or domain part)
 #domain-needed
 # Never forward addresses in the non-routed address spaces.
 #bogus-priv

 # Uncomment these to enable DNSSEC validation and caching:
 # (Requires dnsmasq to be built with DNSSEC option.)
 #conf-file=%%PREFIX%%/share/dnsmasq/trust-anchors.conf
 #dnssec

 # Replies which are not DNSSEC signed may be legitimate, because the domain
 # is unsigned, or may be forgeries. Setting this option tells dnsmasq to
 # check that an unsigned reply is OK, by finding a secure proof that a DS 
 # record somewhere between the root and the domain does not exist. 
 # The cost of setting this is that even queries in unsigned domains will need
 # one or more extra DNS queries to verify.
 #dnssec-check-unsigned

 # 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, SIP, XMMP or Google-talk.
 # This option only affects forwarding, SRV records originating for
 # dnsmasq (via srv-host= lines) are not suppressed by it.
 #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 from 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

 # Example of routing PTR queries to nameservers: this will send all
 # address->name queries for 192.168.3/24 to nameserver 10.1.2.3
 #server=/3.168.192.in-addr.arpa/10.1.2.3

 # 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 double-click.net to a local
 # web-server.
 #address=/double-click.net/127.0.0.1

 # *.dev.local to docker
 address=/.dev.local/127.0.0.1 # docker with virtual box on mac

 # --address (and --server) work with IPv6 addresses too.
 #address=/www.thekelleys.org.uk/fe80::20d:60ff:fe36:f83

 # Add the IPs of all queries to yahoo.com, google.com, and their
 # subdomains to the vpn and search ipsets:
 #ipset=/yahoo.com/google.com/vpn,search

 # You can control how dnsmasq talks to a server: this forces
 # queries to 10.1.2.3 to be routed via eth1
 # server=10.1.2.3@eth1

 # and this sets the source (ie local) address used to talk to
 # 10.1.2.3 to 192.168.1.1 port 55 (there must be a interface with that
 # IP on the machine, obviously).
 # [email protected]#55

 # If you want dnsmasq to change uid and gid to something other
 # than the default, edit the following lines.
 #user=
 #group=

 # If you want dnsmasq to listen for DHCP and DNS 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=
 listen-address=127.0.0.1
 # If you want dnsmasq to provide only DNS service on an interface,
 # configure it as shown above, and then use the following line to
 # disable DHCP and TFTP on it.
 #no-dhcp-interface=

 # 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"

 # Uncomment this to enable the integrated DHCP server, you need

 # don't need to worry about this.

 # If you want dnsmasq to detect attempts by Verisign to send queries

 # Change the following lines if you want dnsmasq to serve SRV
 # records.  These are useful if you want to serve ldap requests for

 # See RFC 2782.
 # You may add multiple srv-host lines.
 # The fields are <name>,<target>,<port>,<priority>,<weight>
 # If the domain part if missing from the name (so that is just has the
 # service and protocol sections) then the domain given by the domain=
 # config option is used. (Note that expand-hosts does not need to be
 # set for this to work.)
