Workflow to display the current DNS

[GamerChase]

Wondering if it's possible to build a workflow to display the current DNS settings, either as feedback into Alfred or a Notification Center output. I'm not looking to change the DNS (I can do that manually, if I have to). But I use Unblock-US.com to view region-specific content, and I want to be able to quickly check that the DNS settings haven't reverted back.

 

Thoughts?

Yes it could be done. A quick Google will show that you can read /etc/resolv.conf (using cat or whatever other method you want) and get the current DNS settings.

So this is what I get out of Terminal, when I enter the "cat /etc/resolv.conf" command.

domain phub.net.cable.rogers.com

nameserver 208.122.23.22

nameserver 208.122.23.23

 

What I have no idea how to do is to get Alfred to pull the "208.122.23.22" and "208.122.23.23" out and post them into Notification Center or back into Alfred.

servers=( `cat /etc/resolv.conf | grep nameserver | cut -d " " -f 2` )

echo "${servers[0]}"
8.8.8.8

echo "${servers[1]}"
8.8.4.4

Dude, that's perfect.  Thank you so much!
