Works fine for and hour or so but breaks my dnsmasq so I'm unable to obtain IP 
on wifi.

I experience same problem. Couldn't connect to my WiFi after a while :-( 

Really want this to work globally

I noticed this happening to me as well, however I was thinking it was a 
configuration error only I would experience. 

The fix for me was to go to the DHCP settings and ensure

Gateway: Make sure this is not blank
DNS: Make sure the only entry is that of the router you run this script on.

For me, both the gateway and the DNS were blank. When wifi clients connected 
they would try then fail. After the changes (and applying them) wifi clients 
connected without any issue. Reply back if this works.

I'll look into this tonight and post laster for verification.

FYI i should clarify for those that don't have a strong understanding of TCP/IP 
addressing.

The Gateway IP is that which the clients will use when exiting your network 
(usually to the internet). It is almost always that of your ASUS router. So if 
you access your ASUS router at http://192.168.1.1, then the gateway you will be 
specifying for DHCP client settings will be 192.168.1.1

Similarly the DNS server will be that of your router - 192.168.1.1, the router 
will be accepting your DNS requests (converting something.com into an IP 
address) and if it cannot fulfil them, it will forward those onto your ISP DNS 
(or whatever you have defined as your WAN DNS server, if unsure use 8.8.8.8 and 
8.8.4.4 as your WAN connection DNS - NOT YOUR DHCP DNS)

All this script is doing is effectively returning a bad ip address for DNS 
requests for Advertisements and malware. This causes the request for the image 
or file to fail, and you are left with a wonderful ad-free experience.

Confirmed. All is good after manually reverting default gateway and DNS server 
to previous values.

Sorry, can't post it as I (or someone from this project) haven't test it.
But I've looked at your code and fixed it a little...
https://dl.dropboxusercontent.com/u/44733876/tmp/adblock.sh
(https://dl.dropboxusercontent.com/u/44733876/tmp/resourses.txt)
Usage: ./adblock.sh /path/to/file/with/links.txt -r

So it reads links from given text file. http and https protocols are supported. 
(openssl binary is required for https).

For example:
./adblock.sh resourses.txt -r

Pls, let me know if it works or any fixes needed...

My take on adblocking might be a bit heavy compared to the other ones
