with ping) inevitably stopped working at some point a few hours after boot. Despite all that, DNS resolution in general (e.g. In my case, everything else was fine: mDNSResponder was running and working, host/ nslookup worked, both /etc/nf and networksetup reported the correct DNS servers, etc. In any case, let us know the exact outputs of these commands. The power of dig comes from the fact that you can specify what type of query you want to perform (Among other things). 2 IN A 184.24.141.15Īs you can see, dig is much more "verbose" (which is good to debug what the heck is going on).

NSLookup is an old command (that was supposed to be deprecated some years ago and replaced by DIG, but its easy to use syntax was too good to kill I guess.), its "replacement" is dig, a much more powerful command, whose syntax is more crazy.ĭig ANd here's the output: $ dig > DiG 9.7.3 > (1 server found) Nslookup "host to resolve" "DNS server to use".

Once things are working, you can run dnsmasq without the -no-daemon and -log-queries options, so it will start in the background and you don't need to keep a Terminal window open. Things should begin to work nicely again. Open Network Preferences and make sure that 127.0.0.1 is the only DNS server (network preferences -> advanced -> DNS -> add 127.0.0.1) Run dnsmasq with sudo dnsmasq -no-daemon -log-queries -C nf. Put this in a nf file that is in the same directory as the nf file (nb: not /etc/nf): nameserver 8.8.8.8
