# Configuration file for dnsmasq. # # Format is one option per line, legal options are the same # as the long options legal on the command line.

Setting this to zero completely disables DNS function, # leaving only DHCP and/or TFTP. #port=5353 port=53 # 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 proxy-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.
