# 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 three 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 # Reply to reverse queries for addresses in the non-routed address # space with the dotted.quad address bogus-priv # Filter useless windows-originated DNS requests 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.
