32 # Configuration file for dnsmasq.

34 # Format is one option per line, legal options are the same
35 # as the long options legal on the command line. See
36 # "/usr/sbin/dnsmasq --help" or "man 8 dnsmasq" for details.
37
38 # The following two options make you a better netizen, since they
39 # tell dnsmasq to filter out queries which the public DNS cannot
40 # answer, and which load the servers (especially the root servers)
41 # uneccessarily. If you have a dial-on-demand link they also stop
42 # these requests from bringing up the link uneccessarily.
43
44 # Never forward plain names (without a dot or domain part)
45 domain-needed
46 # Never forward addresses in the non-routed address spaces.
47 bogus-priv
48
49
50 # Uncomment this to filter useless windows-originated DNS requests
51 # which can trigger dial-on-demand links needlessly.
52 # Note that (amongst other things) this blocks all SRV requests,
53 # so don't use it if you use eg Kerberos.
54 # This option only affects forwarding, SRV records originating for
55 # dnsmasq (via srv-host= lines) are not suppressed by it.
56 #filterwin2k
57
58 # Change this line if you want dns to get its upstream servers from
59 # somewhere other that /etc/resolv.conf
60 #resolv-file=
61
62 # By default, dnsmasq will send queries to any of the upstream
63 # servers it knows about and tries to favour servers to are known
64 # to be up. Uncommenting this forces dnsmasq to try each query
65 # with each server strictly in the order they appear in
66 # /etc/resolv.conf
67 #strict-order
68
69 # If you don't want dnsmasq to read /etc/resolv.conf or any other
70 # file, getting its servers from this file instead (see below), then
71 # uncomment this
72 #no-resolv
73
74 # If you don't want dnsmasq to poll /etc/resolv.conf or other resolv
75 # files for changes and re-read them then uncomment this.

92 # than the default, edit the following lines.
93 #user=

95
96 # If you want dnsmasq to listen for DHCP and DNS requests only on
97 # specified interfaces (and the loopback) give the name of the
98 # interface (eg eth0) here.
99 # Repeat the line for more than one interface.
100 interface=eth0
101 # Or you can specify which interface _not_ to listen on

104 # you use this.)

106 # If you want dnsmasq to provide only DNS service on an interface,
107 # configure it as shown above, and then use the following line to
108 # disable DHCP on it.
109 #no-dhcp-interface=
110
111 # On systems which support it, dnsmasq binds the wildcard address,
112 # even when it is listening on only some interfaces. It then discards
113 # requests that it shouldn't reply to. This has the advantage of
114 # working even when interfaces come and go and change address. If you
115 # want dnsmasq to really bind only the interfaces it is listening on,
