I'm using OS X Mountain Lion. I'm using dnsmasq
to set up wildcard localhost domain names, such as http://local.dev, to point to localhost. But I have to add 127.0.0.1 in my system preference -> network settings.
After I set up 127.0.0.1 as the DNS server, the ISP's default DNS servers were over wrote by mine. This was preventing me from accessing websites. It's not a big deal when I don't move my computer, I could manually enter the ISP's DNS server. But if I change places, the ISP's DNS changes.
I also tried to use google's DNS server, but it's not working in some instance. How can I reserve (or update) the ISP's DNS server without deleting 127.0.0.1 as a DNS.
Thank you in advance.

Yep. You can do this,
/etc/resolver
is your friend.$ man 5 resolver
:Simply put you can place
nameserver 127.0.0.1
inside a file you create called/etc/resolver/dev
You'll need to reload/restart. It'll then direct any requests to
*.dev
to your local nameserver.Your network connection DNS remains on automatic, so it will cope with any changes in your environment.

dnsmasq
setup details.
