I'm running dnsmasq on a 2016 MBP running Mac OS Sierra (10.12.1) but I'm unable to ping any .dev addresses despite having what I believe is the proper config. Running dig does return sane output.







My DNS server list in System Preferences has only one entry pointing to

When I run dig on a .dev address I get the following output:

; <<>> DiG 9.11.0-P1 <<>> test.dev
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 36126
;; flags: qr aa rd ra ad; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

;test.dev.          IN  A

test.dev.       0   IN  A

;; Query time: 0 msec
;; WHEN: Mon Dec 19 23:13:20 PST 2016
;; MSG SIZE  rcvd: 42

I'm able to load external sites like google.com perfectly but if I try accessing a local web server or even pinging a .dev address it fails.

Help would be appreciated!

  • Thanks for the suggestion. I've removed the line but it still doesn't work unfortunately.

  • Which method do you use to assign host names? The /etc/hosts or /usr/local/etc/hosts/ file method?

  • I'm not using either of those files. I've configured dnsmasq in such a way that it should be routing all traffic which matches the .dev pattern to localhost. This means I shouldn't have to manually enter every domain I want to reroute in my hosts file.

  • Please add this part of the dnsmasq.conf file to your question.

Your dnsmasq daemon isn't properly configured.

Your external resolver is working: all queries to non-dev hosts/domains are forwarded to 3rd-party DNS servers with the resolv-file=/usr/local/etc/resolv-dnsmasq.conf line - in your case the configured file contains two public Google DNS servers.

Your internal resolver doesn't resolve internal names though.

The line address=/.dev/ or better address=/dev/ will redirect any *.dev query to the host An internal resolver is not needed then and the internal name server defined in /etc/resolver/dev is useless.

Compare this with the example in the dnsmasq.conf file:

# Add domains which you want to force to an IP address here.
# The example below send any host in double-click.net to a local
# web-server.

Any query for *.double-click.net will be redirected to and to an arbitrary website served at localhost.

I strongly recommend to define a hosts.config file and enter/define all necessary hosts there:

Add a line addn-hosts=/usr/local/etc/hosts/hosts.conf in dnsmasq.conf. Then add a folder with sudo mkdir /usr/local/etc/hosts and create a file hosts.conf

sudo nano /usr/local/etc/hosts/hosts.conf

with the following content:   localhost   test.dev   test2.dev

After saving the file reload your dnsmasq daemon.

If you want to use different IPs for your host names e.g.:   localhost   test.dev   test2.dev

you'd have to add additional IPs with:

sudo ifconfig lo0 alias up
sudo ifconfig lo0 alias up

    I understand your point about the internal resolver being useless but don't understand the need for the hosts.conf file. If dnsmasq was behaving correctly it should direct all dev addresses to localhost. Having to hardcode all the domains and subdomains in a host file takes away the benefit of using dnsmasq.

  • @Steve I don't know your setup but often (web-)developers use several different hostnames on the local machine and/or additional hosts in VMs or on other real machines. Then you need an easy to configure and lightweight DNS/DHCP server like dnsmasq. IMHO the purpose of dnsmasq is not to resolve local-only hostnames to localhost. This can be done easier by editing /etc/hosts directly with sudo nano ... or with a GUI like Gas Mask.

    The issue with the host file approach is that it breaks down if your web application relies on dynamically generated subdomains like the one I'm working on does. dnsmasq has been able to achieve my goal of redirecting everything with "dev" on machines running Linux in the past with the same config.

  • @Steve 1. DNS resolution is known to be wonky in OS X. 2. I don't think that the "black hole" name resolution approach follows an RFC standard. 3. In my test VM "name resolution" worked with your config for various virtual apache hosts (test.dev, test2.dev etc), but IIRC also ping. I may test the ping-thing again, I returned to a saved VM snapshot without dnsmasq installed though and it takes some time to set it up again to further investigate the issue.

  • I'm not sure what changed but after installing an update to Mac OS dnsmasq appears to be working as it should.

The .dev TLD is no longer usable by developers as a private TLD. I ran into this, and had to change things to use ".priv" or something else instead. The ".dev" TLD is no longer a private thing, as it now belongs to Google, and is treated in a special way by Chrome and other browsers.

Following is a clip from the following article: https://www.tomshardware.com/news/google-enforces-https-tld-hsts,35564.html

"Google announced that 45 of the top-level domains (TLDs) it recently purchased, including .dev, .app, .eat, and so on, will enforce HTTPS security, guaranteeing that all connections to sites using those TLDs will be over encrypted channels."

  • ths .test tld is great for local, and in fact designed for exactly this case!
