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 184.24.141.15ДЄs 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.Дig ANd here's the output: $ dig > DiG 9.7.3 > (1 server found)

Nslookup 'host to resolve' 'DNS server to use'. So to resolve using google's server, you'd type:

Last but not least, your Mac comes with two important DNS commands, nslookup and dig. If it doesn't, then you can start digging what your current user has that could be causing the issue if it also fails, then you know this is something more 'system' related.ДЄlso take a look around the Console to see if you can spot something that may be related (and would like to paste around here).

Have you tried using 8.8.8.8 (google) or any of the OpenDNS 208.67.222.222 or 208.67.220.220?ДЇinally, a usually nice test consists of creating a blank user and seeing if that new user exhibits the same problem.

Since you've tried virtually anything that comes to my mind, I'd like to ask you: Name resolution under OSX (and UNIX in general) is taken from the IP addresses of the DNSs in the file located in /etc/nf (which OS X automatically generates as far as I can remember). 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

Build dnsmasq (download the tgz and make or brew install dnsmasq).

So, for now, I've 'solved' the problem by running dnsmasq locally. I've experienced the same problemвЂ¦ And while restarting mDNSResponder does seem to 'work', restarting it a couple of times every hour sort of sucks. # or the DNS query routing mechanisms used by most processes on

This error is most often caused by having no connection to the Internet or a misconfigured network. DNS is the network service that translates a website's name to its Internet address. The server at can't be found, because the DNS lookup failed. It doesn't work, see Google Chrome output: Have you tried using 8.8.8.8 (google) or any of the OpenDNS.I've also tried Google's 8.8.4.4 and 205.171.3.65 (which I found from GRC's DNS Benchmark to be the fastest).

They can use DNS in a Windows 7 virtual machine (VMware Fusion 3.1.3) running under OS X.

Some of my coworkers are having troubles on their Macs - DNS resolution does not work under Mac OS X.
